Mm

from what i understood, he was kinda thinking of it like "if i am going to be hated at the end of the day then im gonna make him rEALLY REALLY hate me and be done with everything that has to do with me or work because i atleast wanna stop the mess i started with just me and me alone"

Why he did it: first he dislikes uke and wanted to screw him over, then started to actually be interested in uke, and then reality hit him in the face: what he did is so awful that the uke could never forgive him nor would uke ever come to like him back (but our spineless uke eventually proved him wrong, ugh).

SO instead of asking for forgiveness, he decides to do the opposite: be as terrible and hurtful as possible, so that the uke will be forced to carry the trauma of being betrayed and sold in avs with him for the rest of his life (and possibly distort again his view of gays so seme will become the only man to ever sleep with uke). Basically wanted to remain in uke's heart one way or another, when love and being a couple no longer was an option.

I get it. I interpreted the same thing but it didn't make sense just because of how these mangas usually go, 5 chapters and everything should be resolved in the last chapter but that aside, its not the last chapter lol
I know there are at least 5 more chapters after the last one, they even include a rival and ok, maybe the author didn't know or planned that and the magazine ask them to do more but still why use it to develop a little bit more because I literally don't understand when or why the seme fell in love.
And thank you for answering!! (⌒▽⌒)

Sorry for the late reply I understand now. Bottom answer its the seme its a as.....
Still what caught me off its that there are more chapters so like why not develop the conflict and the characters a bit more? just a thought but whatever maybe I'm looking too much into it
