guess its not it, but some parts are similar, like abuse (physic.), runaway together and also a scene where they walk home together

same kind here. they run away together (though it was only during holidays), abuse and then the gap where we see them together as adults (not talking about kids but about a cat^^) http://www.mangago.zone/read-manga/koi_no_mannaka/
Thank you so much. It's not either of those but I've not read them yet. So new manga for me to devour.
I've found the one I was looking for after delving into my folder. http://www.mangago.zone/read-manga/shounen_tsubaki/
Thank you so much for your response again.
It's this one http://www.mangago.zone/read-manga/shounen_tsubaki/
All I remember is the ending or the extra of the yaoi manga: the main characters were together and living in a small town or village. I think one of them was working as a teacher. And it was a very sweet scene of them walking home and talking about the students and their relationship( maybe).
I remembered they went through some hardships getting together. The uke might be being sexually or physically abused by his father (or stepfather or guardian). They got together and ran away at the end.
The little scene from extra just popped into my head recently and it's been bugging me. I'm looking through my own lists and archives too but if anyone could help, I would really appreciate it.
Thank you so much.
