I agree, but I mean maybe he has lost hope because he tried to start fresh a while back and it didn't work. Maybe he thinks it's like hopeless.
Yeah, i get what you mean. He definitely thought that it's hopeless, but the truth is that he didn't try 'for real' to escape from everything because he had his worries about Dong Hyun getting hurt so he couldn't really leave him and his past. This time he needs to try for real(^～^)
Yeah, you're right. Well let's see how far he fucks it up until he sees that he should have stayed.
Kyung Soo shouldn't stay with neither of them.
Reasons:
1. It's absolutely confirmed and clear that Yule is suffering from some sort of mental illness, making him extremely dangerous. He totally abused Kyung Soo in the worst way possible, breaking him both mentally and physically. You can't blame Kyung Soo for wanting to return to Yule, after being threatened and manipulated by him. Yule was planting fear and threat in his mind, making Kyung Soo paranoid.
2. Dong Hyun may have good intentions, but he can't completely understand Kyung Soo since he can't really know to what kind of torture he's being through. While Kyung Soo, has some feelings for him, the main reason he clung to Dong Hyun was because he was in need of a person ''lay on'', a person to comfort him, also because he was feeling guilty for putting him into so much danger due to Yule's obsessiveness. Yes, Dong Hyun does put Kyung Soo's mind in peace but at the same time reminds him of the ''past'', making the feelings of fear, guilt and suffer come back to him.
In conclusion, Kyung Soo should leave the past behind and every person associated with it, and make a new start. I don't say that he should jump into oblivion, but he should definitely try to move on, to start completely fresh. Sometimes escaping from things and leaving them behind isn't bad. Especially if they're traumatizing and unpleasant.
That's just my opinion. No hate intended.
