Lemme fill you in cs I’ve been waiting for the side couple’s story.
Seme(black hair) hired uke(blonde) to pretend to be his boyfriend to cut off his persistent and abusive ex. Stuff happened and seme seems to caught feelings for uke. They ‘broke up’ for a bit and met again after uke found out some has been hiring him to do jobs anonymously. Btw that’s how uke made money for living. Also uke used to have a thing with the uke from main couple.

I want to re-read the chapters of the side couple because I can’t remember what happened
