I hate the seme too, but the way he cares for Yeonwoo afterwards. Maybe consider to continue reading it. Its good :)
Have you read the current chapter? Or you read from novel? Because once the seme cheat I really don't care about his character development or whatsoever it's really turn me off. And what's make me hate the seme more because he just want to marry the uke because of the sex. I really hope uke run away and end up with someone else but I know it's really impossible
I am not sure about the cheating part since they are never in relationship ┑(￣Д ￣)┍ but i can’t tolerate the part when seme raped the uke, and when he found out uke is pregnant he still has the audacity to ask the uke to marry him. What a jerk. Not even apologizing first. Real jerk.

Okay I read raws and translate it from google translate lol and I'm really really pissed with the seme. So when both found out that uke is pregnant, the uke lie that the baby is not seme's baby and the stupid seme really believe that lol. Then, the seme ask uke to marry him omg the audacity..... the uke angry and ask why the hell seme want to marry him?? And what pissed me off the most is the seme's answer he said becuase sex with the uke is good lol I stop reading it because it really made me want to choke the seme
