Yes, I agree so much. I was thinking that the wife maybe found out about Kwon loving a man and has since then despised him. Either way, Yoon definitely reminds Kwon of his friend.
I think so too. this is why he send mix signels to him all the time, cause deep down he really wanted Yoon without even see what he was doing. he was in deep denial but he fall in love with Yoon XD
lmao i was laughing when seeing the ex wife hoping all miseries for kwon and she swore to take as much as she can XD
he's scared to ever experience the loss ever again, imo. that's why he always stated that their relationship is sex partners, he tried too hard to draw the boundary so he won't get hurt
i have a hunch that this hyuksoo guy was someone kwon fell in love with before. but he died when he was sent to some civil war country as a journalist. since then on, kwon swore to never fell deep into a person ever again because it's hard when a relationship ends (either by death or separation like breakup). when kwon was having a conversation with yoon, he talked about this 'friend' with such an adoration that's why i could come with conclusion
well i doubted that at first because kwon had been married with a woman, but maybe the reason why he was so cold towards his ex wife is because of kwon actually fell for hyuksoo who's a guy, but he was in denial, so he buried his feelings. but since then on, he couldn't love anyone else properly and it ended up hurting the ex wife, so they are divorced now
lol these only my theories so don't take it srsly
