Gu Jin wakes up to find himself transmigrated into the male lead of a youth drama? Rich and...

The house is occupied by busy parents, and there's also a younger sister who's a school beauty queen and cries to wake him up every day.

After transmigrating, Gu Jin smiled calmly and decisively flipped the table. Whoever wants to be a simp can have it! Tearing apart a scheming woman, berating a love rival, holding hands? Right now, all I want to do is study!

"Brother~ will you come to my room to help me with my homework again tonight?"

"???"

"Isn't something wrong with how this plot is developing?!"
