Short answer: uke became the madam of the group.... For a bit at least. Seme, I think, would dissolve/get out of the group. And I think uke's feeling is open-ended, not stated if he did love or is in love with seme.

Drama: uke will be blackmailed by his brother to steal info about the group's money. Brother promised that if uke helps him he, the brother, will leave and never bother uke again. The heist was planned and successfully executed. Things happened, brother kidnapped uke and his besties beat uke to a pulp, told uke that seme would never believe that uke was a victim and is instead a willing accomplice. Because of trauma and torture, uke believed them and tried hiding from seme by motel surfing while trying to heal. Uke was genuinely scared out of his mind (since the story was told from his pov, I was also scared for him). Turns out seme knew all along and let the heist succeed so he can remove the rats within the group (brother was helped by various members), but didn't expect that uke was still terrified of him (gee, i wonder why) and was actively searching for uke since he is his wife (duh). Angsty sx scene.

(This is all I remember from the short novel)

Uke starts liking the privileges he gets as the seme’s “wife” and embraces the role. The gang respects him. The seme gets back at the aunt and her man by gambling, and then the man gets beat tf up. At the end he moves him into his house and has a whole completely yellow themed room set up for him. He also meets the semes sister at the house and she scolds the seme to treat the uke better.

thanks, now after reading this im dropping this lol

ohhh, hope we get answers if he did love him or not.(( open ended endings or feelings of a character makes me overthink sometimes xD))

Yes they love each other by the end.
Declared themselves. We get a small incite from ml pov and shows he fell for mc instantly.
