After I Became the Fake Heiress, My Three Oppas Dropped the Act

[Transmigrate into a book + All the guys are sis-cons + Romantic rivalry + Sweet daily life]

Kim Seo-yeon transmigrates into an old Korean drama as a fake heiress from a chaebol family who bullies the female lead and eventually ends up in a women's prison. Worse, the original character's three oppas are all die-hard fans of the original female lead, and will someday turn against their own sister for the greater good!

To stay alive, Kim Seo-yeon frantically saves up to buy a house, planning to grab her things and run the moment her background is exposed.

Who would have guessed that her background would come out early, revealing that she's not a fake heiress at all, but the daughter of her chaebol father's beloved first love!

The three older brothers who had been ready to stand up for the original female lead look at her completely differently now.

The eldest, who was supposed to serve God, renounces his vows on the spot and parachutes onto the group's board of directors, keeping her close under the pretext of teaching her about business and an MBA.

The aloof, ascetic second brother takes off his black robe, puts on a white coat, becomes a pediatric attending physician, and turns into "Director Kim's" most devoted lackey.

The third brother, who's been living abroad, rushes home overnight and becomes a top chef, personally preparing all three meals each day.

Watching the mad power players close in and brawl over who gets to dote on her, Kim Seo-yeon clutches her secret identity and trembles. "Weren't you supposed to turn against your own sister for the greater good? Keep it down, all of you!"
