Also, Taejung suffering even after he broke things up is understandable. I mean, they've been together for 30 YRS and been dating for 8 YRS, not including the time Joyoon went unconscious. Yet he hurt Joyoon (which he clearly did not like), and that meant hurting himself too. Their relationship isn't merely just a romantic one. Friendships that are established like that for so long is very hard to let go, especially if it is a genuine and true relationship.
People be like "I hope the ex suffers" etc. etc. I bet most of you would've done worse if you were in his position. Joyoon never deserved what happened to him, but does that mean Taejung deserved his? I don't get you people.
Just because he picked Youngwoo over Joyoon, doesn't mean he deserves to suffer. Yes, he hurt Joyoon, emotionally and physically, but did he really wanted to? Did you even also consider the damage blow in his mind all those years of waiting and suffering for Joyoon? Is it easy for you to chose between a lover who went missing for years and someone who were there all those years??
Cut some slack people. If you hate him, then go ahead, but don't wish for their demise. We already felt how damaging it was for Joyoon, we don't want another one to feel too. But I guess you wouldn't since you already wanted the other party to continue damaging. People who don't consider things and straight want others to suffer are so damn hateful. Tsk -_-
Also, it's nice to talk with straightforwardness and frank so people can realize, but Kwonjoo is not in anyway better. He is still not fully recovered, and clearly was still suffering from the after effects, but his words are so frank and straightforward, it might damage someone if this were in real life. His also damaging Joyoon. At this point, I personally can't see someone who deserves him.
PS. I think Youngwoo had trouble, or is having trouble with his mental health. It feels like he is afraid to be left alone. Something might've happened before everything went south for all of them. He actually kinda reminds me a little of Chowon from LIAI.
