Finally found it after searching for like 5 hours.
Hello! (=・ω・=) I was looking for yaoi manga in which the seme (or uke, i don't remember clearly) has a mind of a kid? He's really clingy and needs attention and behaves kind of like a child when he doesn't get what he wants and that state of his was presented as some kind of condition? After falling in love with the uke and sleeping with him his condition disappears and he starts to behave like an adult. Does anyone know what's this manga's name? Thank you so much in advance!
