It's explained earlier but he can't break up with her besides the fiance already knows and doesn't like him either It's a contract marriage type thing and I also believe the fiance has someone she likes if I remember correctly
The fuck the seme is horrible (╬￣皿￣)凸
He's still asking the uke to be a mistress so yeah, he's horrible. Seme doesn't understand the feeling of being a mistress or a secret lover hurts the uke.
Poor baby （￣へ￣）
So he basically asked the uke to be his mistress. Yeah no wonder the uke is so hesitant, you can't be casual with someone who you mutually have feelings for. Plus
Seme does not even have any intent to break up his engagement with his fiance.
