it's nice to see that kanchan has good insight into how shitty he was and what he did to yumi and that he took steps (change job, avoid relationships) to actively avoid being put into the same situation again. I'm not saying that his method of controlling himself is healthy, but it's important to have insight and know what you're doing is wrong. It's the biggest step towards change and recovery. I hope the seme is able to help him atone and be a better person in a more positive/healing way.
whaaat there's no sequel? I need to know the bro's story!
I think that every time I read this. I totes ship him and the manager.
