I want a yaoi where the small uke grows to be tall and big and ends up as the seme. If you could point me in the right direction that would be lovely! ^___^

Mangas I've read that are similar to this plot but not exactly would be Kawaii Akuma. Read it but its not really what I am looking for since he was seme to begin with 🙂

iirc chapter two of Tojitsuki Hajime's manga Shiro Neko is like that--two young boys are friends until one moves away, but then he moves back to find the sweet little boy he always protected grew up to be a big delinquent.

(It's only that one chapter, but the entire book is really cute imo.)

Well a manga that kinda fits is Ai no Kotoba wo Uragaeshi
The two first chapters are about a guy that finds a kid and ends up raising him. When he grows up he is the seme XD

Thanks al but I already read it. But thank you for reminding me about it! <3

Kusatta comes to mind... and I'm sure I've read others like that, but they were mostly forgettable oneshots. Sorry. 🙄

I suggest Complex.

Read Tsuyogari by Nekota Yonezou. Ch 5 is when they were young and the extra is what I think you're asking for ^^
The whole manga is really good so read the rest if you get the chance!
