Honestly.

I don’t think Seme wants to back out or anything but he’s probably scared of the future. I mean the Uke is older than him and he may feel scared that the Uke will realize that he’s too immature for him and all that. I hope they talk it out sincerely and yea. I really love them. And these things happens in relationships it’s inevitable and it can’t always be prevented especially if one person in the relationship suffers from internalized hatred or smthg.
