im a sucker for that trope
https://www.mangago.zone/read-manga/incidentally_dyed_by_spring_s_love/
so basically its also reunited trope, they met in university and the bottom (the mc) starts developing feelings for the top as they get through piano lessons - their deal was that the top would teach him how to play one particular song to the bottom and once thats done, the piano lessons r over. before it ends tho, top says hes going to study abroad, bottom is obviously kinda heartbroken and sad but then top says lets just sleep together. so bottom who likes him, agrees but thinks that the top is only using him for his body and never had sincere feelings. they never see each other after this and top goes abroad. then theres like an 8 yr time skip. its more melancholy than sad and the way that author words things r super poetic
can you please recommend me a good manhwa/manga that has unrequited love trope please please i am down bad with that kind of thing lol
