Suppressant didn't work on him, and didn't we see him he buy like a bucket full of that shit in chapter 12?
Dojin literally said that this type of suppressant didn't work on him , which means he tried more than one time and failed
Wtf
I said what I said (⊙…⊙ ) It’s not like old dude didn’t try and stop him. Then having sex again came from when he TRIED to give him the suppressant then after that dude basically fell for him. The same way dude wanted to get pregnant by him
So I think we all know what’s going on. He wants him to stay because he’s starting to like him. But him leaving his like him basically trying to runaway from it. Which isn’t really fair since he was the one that started it cause he wouldn’t take the suppressants.
