i can't remember the title of this manga but i remember there was a sidestory in it that i really liked. it was about a guy who liked a girl who died. she erases his memory so that he won't be sad anymore about her death, but he ends up remembering her anyway and sees her ghost. does anyone know what i'm talking about because i can't remember what manga this was from at all! 🤢

I've read that story too. The guy always cries in his sleep but he doesn't know why and the heroine has long, black hair. Unfortunately I don't remember either.

edit: I did some digging and there's a extra from Mademoiselle Butterfly called Memories of You, that's the one I'm talking about and it may be the one you're looking for too. 🙂

maybe Sora no Otoshimono

Side story in v1 of Mademoiselle Butterfly?

yay! thanks guys, it was the one from mademoiselle butterfly 😀
