Help ?

Hey ! I was wondering if anyone could help me find this yaoi manga. I know the whole story but I can't find it no matter which words I use.
I think that it was an already established relationship. The uke was young, the seme older. The seme was away for a few years and the uke would keep sending him cute pictures of himself because he loved them. Issue is the uke grew up to be buff and big and nothing like the seme was used to, but he kept sending him his old pictures because he was afraid that he would leave him after seeing his new form. The seme eventually gets back and the uke pretends to be a cousin but the lie doesn't last long and they.. Catch up on all those years spent apart . (▰˘◡˘▰)
