SPOILER!

If yall read chapter 52 yall know how selfish seme is, he doesn't care about uke's feelings at all so for yall who thinks he deserves better not at all?
He actually deserves someone who puts him in his place
Doing it outside on bench, stripping uke butt cheeks naked in public space and ignoring his wishes is enough reason for break up but see, this is uke's first time experiencing love, he's gonna fall for it every time, that's how easy can love manipulate someone.
You can see same thing to happen in chapter 55, they're with their friends and bunch of people and seme can't be more obvious, touching uke, saying sus things while looking at him and then running after him to bathroom and kissing him, if this was realistic you know how dangerous it is to live publicly as gay anywhere around the world and yet he's trynna let everyone know, dang.

Seme's character is fine alr, I like obsessive type ngl, it's fiction after all but I hate illogical and selfish characters that act simply by emotions, uke is naive type, type to rely on his partner, he can just go with anything seme wants, that's what is making him actually dumb asf.
