Hyesung being scared and immature is normal I think. That's how scary it is to be a young mother
Exactly! First of all, he suddenly discover he's an omega. And that also after doing it with an alpha while being totally out of control. Then he ended up moving in. (which made him feel like he's being looked down upon) Then he gets pregnant with another subconscious incident. He's suddenly supposed to have a kid for this random rich dude (he has no idea about his feelings) His rough childhood isn't helping much in this situation.
Now add the struggles of pregnancy with this............ I am actually surprised that Hyesung isn't having a downright breakdown instead of acting out like this.
And all this could have been fixed if they both just sat together for a lunch or dinner and talked about their feelings and the situation....
This is their family problem. Let them talk and fix it! Don't interfere! Also, you deserve a punch by Dojin right now for doing this!
Also, it isn't Hyesung's fault! I know he could have been more mature, but he had his reasons. Hyesung having Byul is kinda similar to the problems of teen pregnancy. (IDK how to explain)
