GL. Main character: Jae-yi, Seul-ki. it's a bit different from the kdrama

Woo Seulgi, a sharp-witted transfer student, has no interest in the power games at Chaehwa High-until she crosses paths with Yoo Jaeyi, the school's untouchable queen bee. Known for her ruthless intellect and cold demeanor, Jaeyi finds herself uncharacteristically fascinated by Seulgi's defiance. Their rivalry starts with competitive grades and cutting remarks but soon blurs into something more dangerous.

it's like inspired from the kdrama and instead of Jae-yi running away , she stays with Seul-ki and Jae-yi's father is admitted in a mental asylum(i might had changed some character personality). it includes gl and smut, so if ur sensitive abt tht, get the heck out and I'd u like tht genre- get ready for a gooood time
