Why do some people hate Yoonseul lol It's his first time having feelings for a man, so it's alright if he's confused. You can be mad at him because he kinda lead Kangjoon on but he didn't do it on purpose. People make mistakes, he hasn't done something so bad for people to actually hate him. And even now he didn't even care about those rumors, he just wanted to make sure Kangjoon was alright. He is dumb but not a bad guy.
Lmao Doyun probably didn't even think Taehan had parents too
I bet his Daddy is super rich hahaha typical plot where the son gets out of Daddies supervision to do it on their own then goes back to Daddy to take over the managment of their own big company hahaha remember in the last chapter he's worried if their job is making enough money to provide financial stability. So that's what I'm guessing.
