History Series / Sadakatsiz

* PluckyComicRelief: Mrs. Cavidan is a total gossip who always digs for and reacts to juicy details in the most melodramatic manner possible. She gasps loudly, speculates wild scenarios, and exaggerates stuff shamelessly while remaining reasonably close to the truth. Her behavior is either hilarious, lightens up the mood, or causes some minor MoodWhiplash both out and InUniverse. Characters laugh at her antics, get annoyed at her in a way that's funny, or, like doctor Asya and Gönül, roast her à la DeadpanSnarker. Cavida takes it all in good spirits.

** Haluk Güçlü is portrayed as an OverprotectiveDad to Derin and Demir. However, midway through the first season, it's revealed that he fathered a son with another woman and that he refused to recognize him. This illegitimate son is a deeply unstable individual who then comes back to stir trouble for Haluk's family.

** Ceren starts as a reasonable, confident girlfriend who doesn't feel threatened by her boyfriend Selçuk's ex working at the restaurant he owns. That is, until Selçuk confesses to Ceren that he was never quite able to move on from Nil and ends their relationship. By contrast, Derin, Ceren's closest friend, has been in a similar situation since before her marriage started and is a very ClingyJealousGirl. So, when a heartbroken Ceren goes to Derin for comfort, Derin starts teaching Ceren her ways -- while Derin is mostly good-intentioned, her own lack of dignity and toxic idea of love cause her advice to be awful. Derin convinces Ceren to keep seeing Selçuk by appealing to his compassionate nature. And, when their last encounter leaves Ceren pregnant of him, Derin relentlessly pushes Ceren to cause strife in Selçuk and Nil's restarted relationship. Them getting married only incenses Ceren further.

* BigEater: Suna, the Güçlüs' nanny, is a chubby woman whose weakness is food. And whose it wouldn't be when you work for a rich family? While not an overplayed trait (her being good with kids being far more prominent), it can sometimes be seen in [[PlayedForLaughs light-hearted moments]]. Especially when the Güçlüs' drama becomes too much. For example, when Derin is too unhappy to eat due to marriage problems, Suna silently eats the fruit pie slice Derin rejects (along with the rest of the pie, really). When Derin's mother Gönül goes to grab another slice, she finds none and teases Suna for it. On another occasion, Gönül's friend Cavidan brings spinach pie to cheer Gönül up (she is upset over her daughter slowly ruining her own life). Suna offers herself to take the cake to the kitchen, only for Cavidan to refuse and jokingly say that Suna will sure eat it all before anyone else has a chance.

* ActorAllusion: Creator/CansuDere has the lead role in another production involving a mother figure who is willing to veer into illicit acts and manipulate people in order to ensure her child's happiness and safety. As well as making sure said child stays with her. Coincidentally, the TurkishDrama ''Series/{{Anne}}'' is also an {{Adaptation}} of a foreign work.

''Sadakatsiz'' is the {{Turkish|Drama}} adaptation of the British drama ''Series/DoctorFoster'', directed by [[Creator/NeslihanYesilyurt Neslihan Yeşilyurt]]. Its title translates as "Unfaithful".

** This situation is mirrored by the second season's climax. Asya's revenge on Volkan and Derin has finally become too much for Derin's fragile sanity -- not helped that Volkan, thanks to Asya's manipulations, puts a definitive end to their relationship. Left without schemes or options to force him to stay with her, Derin attempts to commit suicide by throwing herself off the same cliff. She calls Asya to inform her that "you'll finally get rid of me", as well as unintentionally revealing where she plans to do the deed. Asya rushes to the cliff and slowly approaches Derin. Asya plays along with Derin's delusion (she'll have Volkan in her next life) and weakness (Zeynep) to convince her to not jump. Asya also tells Derin that she deserves to be loved and even slaps her when, upon finally managing to embrace Derin, Derin threatens to kill them both. They spend a long time near the cliff's edge, but Asya doesn't leave Derin until Onur and an ambulance arrive. Once Derin recovers, she is very grateful to Asya and remembers that, indeed, Asya has saved her butt from drowning. Again, {{justified}} thanks to Asya being a doctor, though also because she never intended to drive Derin to suicide, only to make her feel as miserable as Derin has made her (Asya) feel in the past.

*** During the time Volkan is courting Derin, he also gifts her white rose bouquets as a show of romanticism. Up until Derin finds Volkan gave the same flowers to Asya, of course. That he is this cheap reflects his personality very well -- he has no problem being double-faced and blatantly lying to people's faces. It's also a hint that he doesn't really see Derin as her own person, he only went to her to feel young, not because he stopped loving his ex-wife. Not that he truly values either woman.

** The show's poster has doctor Asya and her adulterous husband Volkan in a BackToBackPose. This is meant to represent that he went behind Asya's back when he cheated and that they are no longer on the same side. The fact he's turning his head to glance smugly at her also conveys that he's not really remorseful of his feat and that he keeps chasing her. By contrast, Asya is looking forward, meaning that she's done with him and absolutely livid. Furthermore, her ring hand is held up and there's blood coming from her ring. The blood is evidently the broken marriage vows.

** {{Downplayed}} with İpek seeing that she's not a villainous character (more like a misguided kid) but a bad influence nonetheless. Her family life is horrible: her parents are divorced, her stepfather hits her, and his father is a criminal. This causes her to try "adult stuff" (drinking, smoking, sneaking away, etc.) to make her parents pay attention to her. When she meets Ali and Demir, the former's parents are already divorced while the latter's family is having a crisis. She convinces them to attend a college party in a fishy part of the town to have fun and forget their stupid family problems. There, she tries to get them to drink alcohol and convinces Ali to drive (he doesn't have his license) to buy booze. This ends with them suffering a mild car accident together. Later, when Ali's hatred for his stepfather reaches a peak and he throws a massive tantrum (he destroys some of his house's furniture and his console), İpek suggests he blames his stepfather and teaches him how to bruise his own arm.
** Ceren starts as a reasonable, confident girlfriend who doesn't feel threatened by her boyfriend Selçuk's ex working at the restaurant he owns. That is, until Selçuk confesses to Ceren that he was never quite able to move on from Nil and ends their relationship. By contrast, Derin, Ceren's closest friend, has been in a similar situation since before her marriage started and is a very ClingyJealousGirl. So, when a heartbroken Ceren goes to Derin for comfort, Derin starts teaching Ceren her ways -- while Derin is mostly good-intentioned, her own lack of dignity and toxic idea of love cause her advice to be awful. Derin convinces Ceren to keep seeing Selçuk by appealing to his compassionate nature. And, when their last encounter leaves Ceren pregnant of him, Derin relentlessly pushes Ceren to cause strife in Selçuk and Nil's resumed relationship.

* DramaticIrony: Because doctor Asya hasn't started a new romantic relationship after her divorce, everyone wrongly assumes that she still loves her ex-husband Volkan. Opinions on Volkan are the exact opposite, seeing he's married his mistress Derin. The truth is another matter entirely -- Asya is content with living with her son Ali and Volkan is unhealthily obsessed with his ex-wife, so he keeps hounding and harassing her. When Derin goes missing, the rumors cause everyone to suspect Asya and Volkan of having disposed of Derin so they can resume their relationship.

** After becoming Haluk's wife, Gönül adopts the surname Güçlü, thus both of her names start with the phoneme "/dʒ/".

** During the time she's married to Volkan, doctor Asya's full name is Asya Arslan.
** After becoming Haluk's wife, Gönül adopts the surname Güçlü.
** Ali Arslan.
** Aras Ateşoğlu.
** Ayse Ateşoğlu.

* GossipyHens: Most of the women running Tekirda&#287's Charity Foundation are elderly, wealthy housewives with lots of time on their hands. Therefore, in between planning projects, they entertain themselves by sharing the small city's latest gossip and fanning the flames of the rumor mill. Particularly noteworthy are Gönül, who has connections with Tekirda&#287's news media, and Cavidan, who doesn't have an ounce of remorse about divulging even secrets other people confide in her. When doctor Asya joins the Foundation, she initially [[DefiedTrope refuses]] to engage in gossip}}. However, she later learns to [[ExploitedTrope use it to her advantage]] whenever Derin or Gönül is being too obnoxious -- Asya knows both women care a lot about their public image.

** Ali's mother is Asya, whose mother is, in turn, Ayla. All of their names start with "a" and some characters are shared, such as the "l" in Ali and Ayla and the "y" and "a" in Asya and Ayla. In a twist of this being PlayedForDrama, Asya's father's mistress is also named Asya. In fact, he {{invoke|d}}s this trope by naming his daughter after the love of his life.

** During the time she's married to Volkan, Asya's full name is Asya Arslan.

* CallingTheYoungManOut: Because of all the drama stirred by his parent's divorce, Ali develops kleptomania as a coping mechanism. His mother Asya eventually finds out and, after consulting with a psychiatrist friend, decides to retrieve the stolen items from Ali's bedroom and return them to the school on the condition that the thief's identity remains unknown. Unfortunately from her, the opposite happens. Ali's classmates start alienating him, so he's very mad at his mother and decides to go live with his father Volkan. Volkan calls Ali out for his disrespectful, dismissive attitude -- telling him that his mother only wants to help him and that he's hurting her by acting like this.
* DramaticIrony: Because Asya hasn't started a new romantic relationship after her divorce, everyone wrongly assumes that she still loves her ex-husband Volkan. Opinions on Volkan are the exact opposite, seeing he's married his mistress Derin. The truth is another matter entirely -- Asya is content with living with her son Ali and Volkan is unhealthily obsessed with his ex-wife, so he keeps hounding and harassing her. When Derin goes missing, the rumors cause everyone to suspect Asya and Volkan of having disposed of Derin so they can resume their relationship.

** Asya is a calm and collected woman who has a successful career and is genuinely [[NiceGirl compassionate]] toward others. She's respected in her community on her own merits and wants nothing more than to ensure the Private Hospital Asrin runs smoothly and her family's happiness. By contrast, Derin is initially only known for being the ex-mayor's daughter -- she has no job and, when she gets one and respect from her community is mostly due to her privilege and money. Derin is also very prone to lose her composure when she doesn't get what she wants. The nail in the coffin is that Asya knows the infidelity is only Volkan's fault (he doesn't tell Derin he's married at first). Meanwhile, Derin remains deluded that Volkan is innocent and that Asya is the viper trying to seduce him back.
** Selen is an studious girl who is constantly the OnlySaneWoman in her friends' antics and ordeals -- she tries to stop them from being reckless even if she fully understands why they are so upset and calls their parents when they dismiss her concerns or the situation escalates. Meanwhile, İpek is a rebellious teen who cares little about studying and is the first to do reckless, "adult" things such as drinking alcohol and flirting with an older boy. Both girls are cousins and have divorced parents. However, İpek's home life is a lot more chaotic than Selen's, as the former's stepfather is physically abusive and her own father is a criminal. In turn, Selen's mother has a respectable job and instills all of the aforementioned traits in her daughter, while always comforting her because Selen's father left.
* ItsAllAboutMe: Volkan is an egotistical prick who makes every situation about him even if the most affected is another person. He starts a romance with Derin because he wants to feel "young and vital" again, withholding from her the fact he's married and then telling her that he's unhappy in his marriage. He never cares one bit about Derin's feelings and, in fact, doesn't intend on divorcing Asya. After he gets rightful comeuppance from his unfaithfulness (and hitting Asya), he can only lament how his life got ruined, nevermind the fact that his misdeeds cause Asya, the woman he purportedly loves so much, a lot of emotional pain. When he returns from America, he is quick to use his son Ali as an excuse to see Asya and enter her house without her permission. As if that wasn't enough, he just can't shut up about how much he still loves Asya and yearns to become a family with her and Ali again. He keeps asking forgiveness but only harasses Asya and acts like a CrazyJealousGuy, never once caring that she doesn't share his wishes and loathes having to interact with him because of Ali. He demands that his friends inform him of every little detail of Asya's life, getting mad when they refuse. The way he gaslights and shames her is always because she's hurting him and their son Ali. When he's conversing with his friends about their life, he more often than not makes it all about his problems or, if he's "patiently" listened to them, only does so to ask them a favor afterward. When he's caught up with his schemes, he doesn't care who he destroys or hurts -- for example, he ruins the reconciliation dinner 14-year-old Demir set up for his parents just because he's mad at Demir's older sister.
* MirrorCharacter: Asya and Gönül are both mothers who will do anything to protect and support their children, even if it's underhanded and sometimes not quite legal. They are also very cunning, resourceful, and observant, picking up small clues and enacting [[TheChessmaster efficient plans]] to meet their goals. It's extremely hard to rile them up in a verbal confrontation and both are prone to roast their opponent with witty, {{deadpan|snarker}} remarks. Finally, their husbands cheated on them at some point -- Asya's after years of marriage and Gönül's just before they married.

* ParanoiaGambit: During the divorce, Asya is already devastated by her husband Volkan's betrayal, but Volkan wanting full custody of their son Ali (as well as Ali's own agreement) pushes her to pull one of these. She exploits Volkan's aggressive tendencies and his love for their son. She picks up Ali from school early for a trip outside the city. When he doesn't find Ali in the school, Volkan thinks Asya has kidnapped him and confronts her. She shows Volkan a pair of scissors and a tuft of Ali's hair and says nothing. Volkan quickly jumps to the conclusion that Asya has killed Ali (Asya's mother killed her cheating husband) and physically assaults her. As planned, Ali witnesses it all and changes his mind about staying with his father. Asya also uses this to obtain a six-month restraining order against Volkan.

* WeakBossStrongUnderlings: CorruptPolitician Haluk Güçlü is a fat, elderly man who has built his great wealth with lots of cunning, networking, and a heaping of not-so-legal business deals. Whenever he needs some physically-strenuous task to be done, he sends grunts to do it for him -- be it scouring Tekirdağ to search for his missing daughter or threatening someone into submission. The dynamic is {{zigzagged}} with Volkan, his son-in-law, who works for him and is generally obliged to Haluk's bidding; either through manipulation, force, or those rare instances where they actually agree. The thing is, Volkan is not loyal to Haluk and, most of the time, neither he is to Derin, his wife. Volkan is, however, a middle-aged man still very capable of beating the shit out of people and has plenty of aggressiveness in need of release.

It started airing on 7 October 2020 and released its final episode on 25 May 2022.

*** Asya takes her to the cliff her parents suffered DeathByWomanScorned to tell her how that happened. Asya's mother couldn't stand her husband still loving his ex-fiancé, and so killed them both in a car accident when Asya was ten years old. She does this to try and make her see reason, that no matter who her husband loves, her priority must be her baby daughter Zeynep. Sadly, EvilCantComprehendGood, so Derin not only rebukes Asya's advice but thinks Asya is manipulating her with her daughter in order to get Volkan back.

Once Derin recovers, she is very grateful to Asya and remembers that, indeed, Asya has saved her butt from drowning.

* SaveTheVillain: Derin's BatmanGambit has backfired on her by, among other things, revealing that Volkan would rather side with and protect Asya, his ex-wife, than worry about Derin's wellbeing. Desperate, Derin then decides to MurderTheHypotenuse (and herself) by driving a car off a cliff. Said hypotenuse, Asya, manages to pull the handbrake at the last moment, but the car still plunges into the sea. Fortunately, Asya has little trouble swimming out of the car but Derin has broken her legs, so after taking a lungful of air, she returns to free Derin. Unfortunately, Asya runs out of breath and can't make it to the surface. She'd have drowned if not for the rescue team fishing her out and reviving her.
** After Derin's BatmanGambit backfires on her, Asya takes Derin to the cliff Asya's suffered DeathByWomanScorned to try and make her see reason. Unfortunately, the lesson doesn't stick and Derin then decides to take Asya to Sapanca, the place she and Volkan met. Because of Derin's frantic driving and everyone pressuring her to let Asya go, Derin decides to mirror Asya's mother and kill herself along with the woman her husband is still in love with, i.e., Asya. So, she drives to another cliff with the intent of throwing them both off it.
