dudes i need some help with finding a bl webtoon. i was reading it but i keep forgetting the name and i cant find it in my library ;-; it is two seasons, two different stories, but both based around the same book...
i cant recall what happened in the first season, but there was a rushed ending and a proposal hh
the second season was, i believe, had a dude with a mental disorder. he acted like he had a twin brother and the uke believed him, but he didnt actually have a twin; he had DID, and fooled the uke n shit.. the uke was into the "good" personality, but later becomes close with the "bad" personality..? IM PRETTY SURE THERE WAS A DANIEL SOMEWHERE TOO
