Both the fl and ml reincarnate into a novel. Neither of them the other has in the beginning. The ml is a prince or someone like that has black hair and died of an illness in his past life and his character in the novel is sick/weak/second prince?……
I am also trying to find an manhwa which has:
1) ml is cute so he gets mistaken as girl by fl
2) fl is badass
3) ml has crush on fl from the start
4) modern world
5) school
6) fl has black long hair reply
