Hi i’ve been looking for several days for this yaoi where the guys are childhood friends but one of them is secretely in love with the other, i don’t remember the title but i know they lived next to each other and they could even see each other by the window of their room. I also remember that the boy was so in love with his bestfriend that he always took pictures, shirts and other things and kept them in his room. I know that the boy confessed his love and at one moment the other boy found all the pictures and things in the room and threw them away lol, the boy in love was pissed and said « che! » (the japanese way of showing that he is pissed). Sorry I don’t remember if it was a manhwa or a manga.
Thanks for your help and excuse my english if I have made some mistakes it’s not my first language 😀

Is it called “ I don’t dislike you”? Other than that I don’t know sorry 😐 I don’t know any more than that

Thanks for your answer but it’s not the manga that I’m looking for unfortunately

I think it's Natsume-kun wa Nandemo Shitteru
