From left to right are the main characters. Park Yua, Han Sang-Hyun and Yu Suh-Eun.
"Han Sang-Hyun" is a boy that dreams to become a manhwaka, and one day he hears a story that falls like lightning from a clear sky. And that is that he had a fiancée he never knew about. After not being able to win against his grandfather, he goes to the meeting against his will; however the lady he meets seems to be a rich, spoiled girl named "Yu Suh-Eun". After having a fight her, he comes back to his house just to find out that Yu Suh-Eun there?! What? The new house that they'll be staying in is the "Marriage House"? Will Han Sang-Hyun and Yu Suh-Eun break through their families' plans and successfully get divorced!? Not safe for work due to the underlying themes, as opposed to actual content.Premarital Relationship provides examples of:
- Accidental Pervert: Invoked and double-subverted. One of the first "plans" employed in trying to force Suh-Eun and Sang-Hyun together is to have their "marital house" have sound-proof bathrooms, with no locks, hoping that eventually one of them would walk in on the other. Sang-Hyun knocks, gets no response... and turns off the bathroom light, from the switch on the outside, while she's in the shower. She angrily chases him down, wearing a Modesty Towel, and confronts him in the kitchen, while he's cooking. She gets a bit too close to the stove, and some splashing grease causes her to drop her towel, right in front of him.
- Adults Are Useless: The very first thing Sang-Hyun does to readdress his perfectly valid concerns regarding the Arranged Marriage, after confronting his grandfather directly only serves to get him beat up, is seek aid from his parents. They immediately go into I Want Grandkids mode, going so far as to lampshade it, and pretty much ignore everything else. Suh-Eun's parents don't turn up, at all.
- And Then What?: The grandparents who set up the arranged marriage situation suffer from extreme tunnel vision, and are so fixated on making the marriage official, including coitus, regardless of the method, that they can't be bothered to consider what comes afterwards. Had they succeeded with their current approach and mindset, the result would have been nothing but an unqualified and unmitigated disaster.
- Arranged Marriage: A core element of the plot is the arranged marriage between Han Sang-Hyun and Yu Suh-Eun, and their resistance to both the idea and its implementation.
- Censor Steam: Whenever one of the female characters comes out of the bath, this trope is in full effect.
- Deliberate Values Dissonance: The mentality behind Yu Jisuk's attempts to get his granddaughter married to the grandson of the man who saved his life, and micro-managing hers, would have been perfectly acceptable as little as a hundred years ago. In modern times, his mentality and methods are wholly unacceptable, though he utterly refuses to believe it, and has mentally locked himself in an echo chamber where contrary opinions to him are simply not allowed.
- Dramatically Missing the Point: After Yu Seh-Eun's grandfather basically declares "open season" on her, in order to force her to run to Han Sang-Hyun out of sheer desperation, the entire female high-school student body proclaims her circumstances romantic, rather then realize the entire male student body isn't interested in her, but only in marrying into a wealthy family. This is something they don't hesitate to proclaim aloud.
- Expy: Sang-Hyun's grandfather is basically Genma Saotome from Ranma ½ raised as a Korean as opposed to Japanese.
- Lens Flare Censor: Suh-Eun's... more delicate areas are covered with "sunbeams" in the early chapters.
- Nice Job Breaking It, Rivals!: Yuri's schemes to try and "expose" the date and relationship between Sang-Hyun and his Childhood Friend Romance blows up in everyone's face because said Childhood Friend had a Love Epiphany beyond their knowledge.
- Obliviously Evil: The two grandfathers are absolutely and completely incapable of seeing how their actions are making life a living hell for their grandchildren, and when it's pointed out to them, they ignore it when they can, or respond with violence when they can't.
- Parental Abandonment: Suh-Eun's parents never appear in the story, except for the fact that her grandfather and Sang-Hyun's grandfather are mentioned as only producing sons during their respective marriages. Considering she's the heir of Myung Group rather than her father, either they've been disowned for not agreeing with her grandfather's inflexible "ultraconservative" mindset, or they're dead.
- Perfectly Arranged Marriage: Though loathe to admit it, because they don't want to give their grandfathers any credence to the idea that micro-managing their entire lives since before they were born is the right approach, Yu Suh-Eun and Han Sang-Hyun complement each other perfectly, and would likely be Happily Married if their grandfathers didn't constantly meddle and try to rush them by any means necessary.
- Pretty Freeloader: Averted. Everyone who lives at Sang-Hyun's "marital house" takes up a roughly equivalent share of the houshold chores, including dealing with the Obliviously Evil grandfathers.
- Rape by Proxy: Choi Yuri, a romance manhwa artist, is hired by Yu Jisuk to hasten nuptials between Yu Suh-Eun and Sang-Hyun. Her idea of a date, after the Accidental Pervert above didn't work as planned, is to have the two main characters go on a date together which ends with the two of them sharing a one-bed hotel room, that they are forbidden to leave, the Tv-channels set to nothing but porn, arranging Suh-Eun to be completely naked via clothing damage and lack of towels, and drugging Sang-Hyun with unnamed aphrodisiacs without his knowledge or consent. Fortunately, he's Above the Influence.
- Selective Obliviousness: The paternal grandfathers of both the teen protagonists are so busy trying to out "yes-men" each other concerning their plans to force and hasten a coital union between the two minor teens, that they are utterly incapable of even comprehending the drawbacks, flaws, consequences, or even illegality in some cases, of their schemes, and how much hatred and resentment they're breeding. By chapter 18, Suh-Eun has reached the point that she not only desires, but can easily justify shooting one or both of them to make it stop, and they still remain blissfully unaware.
- Sex Slave: How Suh-Eun views her role in the Arranged Marriage scenario set up by her grandfather, and she resents it very, very deeply. To the audience's horror, her interpretation is entirely correct. To her relief, Sang-Hyun respects her boundaries and treats her like an equal with genuine respect, even when he didn't think she deserved it.
- Sexual Extortion: Sang-Hyun's grandfather, with the full blessing of Yu Jisuk, "convinces" his grandson and Suh-Eun to go on the date completely orchestrated by Choi Yuri, and follow the scenario she lays down, to the letter, by threatening to cut off Sang-Hyun's monthly allowance, just as the monthly bills are coming due, on the house that Sang-Hyun and Suh-Eun were forced to move into in the first place!
- Social Services Does Not Exist: It's highly likely that the Korean equivalent of Child Protective Services would like to have some choice words for Yu Jisuk, Choi Yuri, and Sang-Hyun's grandfather if they ever got their hands on transcripts of any communications from them to the minor-child teen protagonists. It's also almost certain they'd want a word or two with Sang Hyun's and Park Yua's parents if their apparent negligence came to light.
- Surveillance as the Plot Demands: The two grandfathers have somehow managed to put into play 24/7 surveillance on the main characters regardless of time or place which they can go back and peruse at their leisure.
- They Just Dont Get It: The two grandfathers simply refuse to let a little thing like the fact that the "happy couple" they've brought into being are minors stop them from trying to rush the coital nuptials, with 24/7 surveillance on them so they can see it happen.
- Wrong Assumption: All over the place.
- Suh-Eun assumes that Sang-Hyun is directly responsible for the Arranged Marriage and lashes out at him, until he proves beyond a shadow of a doubt that he's not, and is actually a decent and very upright guy worthy of her affections.
- The two grandfathers honestly believe that romance-comedy manhwa, which are works of fiction, are accurate portrayals of modern romance, and hire an in-universe famous manhwa artist as a professional relationship counselor to try and convince the two main characters into agreeing to the Arranged Marriage, and go along with her "plans" without any hesitation, even having no issue with the main characters sexually assaulting each other as a result. Heck, they even insist on watching it take place!
- Choi Yuri, the mangaka hired as both a maid and "professional relationship counselor" thinks the term "Hormone-Addled Teenager" applies universally to the entire teen population of Korea, and if she can maneuver two teens of opposite genders into a room, lock them inside so they can't leave, have only porn available to them, and have some creative "clothing damage" render one or both naked, while they've been drugged with aphrodisiacs without their knowledge for good measure, they will invariably be unable to resist the urge to go at it like rabbits in heat.
- Sang-Hyun assumes the fiancée, Suh-Eun, that he's ambushed with, is a Rich Bitch because that's the image she projects of herself to try to get out of the Arranged Marriage.
- Wrong Genre Savvy: Choi Yuri basically thinks she's in To Love Ru and that romantic scheming on the order of Momo or Nemesis will work. Her plans consistently backfire spectacularly as a result.
