This is the one. Its what I was really hoping this one was going to be like

There’s another one called Tsukiatte Agete mo Ii n Dakara ne.

I had accidentally meshed the two stories in my mind

I totally thought you were talking about one I read like a year ago or something. But I don’t think there was bullying in that one. The guys used to know each other in middle school but one of the guys moved away as the other guy got skinny but it turned out the cute guy liked fat guys and still does but doesn’t date them and the guy gets insecure that the other guy is gonna leave him for a fat guy cause he’s not fat anymore. Anyone know what comic I’m talking about? I’d like to re-read it
There’s a similar manga to this where the seme was previously bullied by the uke. The seme loses weight and becomes successful. He tries to date the uke as revenge, but turns out the uke never intended to bully him, but was actually doting on him because he found the chubby seme adorable. I forgot the name, but it was pretty cute.
