History Manga / GirlfriendGirlfriend

* DullEyesOfUnhappniess: Both Saki and Nagisa have this look shortly after Rika forcefully kisses Naoya.

* InsaneTrollLogic: The basic premise of the series really, Naoya thinks the best option for his relationship woes is to just date both girls at the same time. His first and often only solution to any problem is to go straight to the most extreme option possible. Saki isn't entirely convinced his plans will work out, but Naoya is nonetheless determined to prove otherwise.

* ClingyJealousGirl: Both Saki and Nagisa to varying degrees. Saki's the most prominent example, being hyper-vigilant to any sign that Naoya could be falling for another girl. Justified with the fact that Naoya ''is'' openly two-timing her with Nagisa. Natural, she's worried that he's going to either leave her in favor for someone else, or decide he wants to add another girl into the mix.
** In comparison, Nagisa comes off as a more downplayed variation of this trope. She has admitted on a couple of occasions that she'd have preferred to have Naoya to herself, but she's pretty respectful of the fact that Saki was Naoya's girlfriend before she was, and ultimately does her best not to come between them in any way. On the other hand, she plays this trope absolutely straight when it comes to Rika, to the point where she openly [[FreakOut freaks out]] upon learning that Rika had been visiting Naoya at his job without any other customers around.
*** Shino and Rika may also count as examples. Though Rika initially offers to be Naoya's third girlfriend, she eventually does a 180 and tells Naoya that three-timing won't be tolerated, and that he'll have to break up with his current girlfriends if he ever decides to get with her. Likewise, Shino sees Saki as being far too lenient, and claims that she'd never give Naoya the opportunity to fall in love with another girl if she were the one dating him. Of course, these attitudes are pretty much the standard among those who participate in monogamous relationships, and one could make the case that these aren't necessarily signs that one is overtly clingy or possessive.

* ClingyJealousGirl: Pretty much all of the girls to varying degrees, with Saki being the most prominent example. Justified with the fact that Naoya ''is'' openly two-timing her with Nagisa. It's natural to worry that he's going to eventually want to invite even more girls into the relationship.

* ChildhoodFriendRomance: Noaya and Saki have known each other since they were little kids, and have apparently had feelings for one another for years.

* DeconstructiveParody: This harem situation may seem like a dream come true, but there are multiple instances where it's made clear that the girls are either putting up with the harem for the time being or are outright bothered by it. Both Saki and Nagisa don't like the idea of sharing their "firsts" with the other girl, such as with kisses or dating, and Saki especially feels left out at times and is always shown resenting the fact that Naoya openly two-timed her. At the same time, Naoya is determined to make both girls happy even with all those difficulties. It's just that his methods to achieve that tend to make a mockery of a little thing called "common sense". And above that, every person who eventually learns about the poly relationship never think of Naoya as lucky or the girls as sweet--they think everyone involved is an idiot, Naoya for two timing, the girls for ''letting'' him, and any hopefuls idiots for falling for a known two-timer.

* AlliterativeName: Saki Saki, her parents thought it would be cute if her given name was the same as her family name.

-->''"I'll give up on a three***."''

-->''"She gives me weird feelings, even as a woman!"''

* BlandNameProduct: Rika makes videos for "Mytube".

* LoveTrangle: The series begins with the forming of one between Naoya, Saki, and Nagisa after Nagisa confesses to Naoya but Naoya was already dating Saki. Not wanting to reject such a cute wholesome girl, Naoya decides to ask Saki if he can date both girls, it takes a bit of convincing but eventually Saki agrees to the relationship. Later in the series with the addition of StalkerWithACrush Rika and the secretly pining Shino it becomes a Love Pentagon.

* BuxomIsBetter: Part of Rika's popularity of MeTube is her large chest and how her videos serve to emphasize it.

** The biggest is ofcourse Naoya, when he gets it in his mind to do something, nothing in this world will stop him until he accomplishes his goal. The downside is that he is like this with pretty much everything and can be a bit tiring to deal with. Though Shino and Nagisa both end up falling for him because of his steadfast determination, Saki just finds it annoying most of the time.

* ChastityCouple: Even though Saki is pretty obsessed with stuff about kissing and sex, it's revealed that Saki and Naoya haven't so much as kissed since getting together. This even becomes a plot point later as Shino tries to set things up so that Saki and Naoya can have a special first kiss. [[spoiler:The fact that despite every opportunity given and Saki still didn't kiss Naoya starts to give Shino doubts that Saki truly loves Naoya.]]

-->''"I'll give up on a three***."''

* BleepDammit: In a series where sexual references are abundant, it doesn't take much effort to understand that Naoya is saying "threesome" (with the "some" part [[SoundEffectBleep blocked out by the sound of steam from a boiling kettle]]) when he announces his intent to abstain from one.

* AmbiguouslyBi: Both Saki and Nagisa to varying levels. While small, Nagisa had no objection when Naoya revealed he was having threesome fantasies, even revealing she figured that would be a possibility. For Saki though, her relationship with Naoya is pretty much the only thing that keeps her from being considered gay. She freaked out at the cuteness of Nagisa, lamenting that ''she'' wasn't dating her, drools over Rika and her sister, and her friendship with Shino is often more romantic in nature then Saki's time with Naoya.

* ACupAngst: Saki and Shino are both on the small size and its a constant source for angst, especially when they compare themselves to the much more endowed Nagisa and Rika
