Is there a prequel to this??I'm so invested.

I know right? Must be interesting (but painful to see Uke's years of painful memories) hahaha. However, this is what makes it different from the other mangas. I like reading ones where the main couple is established already.

Well thats true but somehow i really wanna know how they got togethr after our seme-san dating tons of girls... And young uke must've been even more adorable!
