Well I have read a numerous stories with assshole semes but this is too much. Hurting someone physically is one thing. But hurting him emotionally even socially is too much. If this is real life, the uke would develop trauma and maybe PSTD from everything that happened to him. But yes, I'm not angry towards the author or anything but I think the plot should improve a little bit. The seme is not a psychopath to begin with and that's what really is disturbing because he's more than the psychopath seme's I've read.
I honestly think this is the starting point of SH's development. It's not easy to change from one character to another one in instant. It could take days, months, and years even in real life. But as I said just SH in this panel with his eyes that speak a lot is a starting point of the character development we've been waiting for. Looking back at previous chapters his eyes are always furious, conniving, anxious and crazy as I may add. This chapter spoke a lot as I think his eyes was more of hoping and kind of relax and relieved. I think this time it is because he was learning to acknowledge his feelings. But the sad part is I think his starting to be territorial. The message for NK's sis just proved that he would kill anyone who will took NK away from him. Well let's just hope this goes on for the better.
