Both the male and female protagonist's native families are not good/Two-way redemption
The male protagonist who is a troubled student who gives up on himself and lives his life / the heroine who is tough on the outside and soft on the inside, is a poppy flower heroine
"She is like a poppy flower, making you sink slowly and eroding everything about you bit by bit."
"Finally the rain stopped and only the sea and the sky were left."
"I want to be a kite in my next life, okay, then I'll be a kite runner'
"Hello, Miss Lin, long time no see, I seem to be more attractive."
"Hello, Mr. Song, you are still as good as before."
Intention: Two-way redemption
