He's his father's son. It's hard to fight your nature. Obviously he pushed it too far. Woo Won is fighting his nature too. Feeling inadequate. How could he not when Seo-an isn't dependent on him like he was when they met? He surpasses him in everything; reliability, competency, success, status, money, connections he's probably even more handsome than Woo Won. Literally he is inferior in every single way and it's eating him alive. Seo-an just lashed out and made him feel like shit, but Seo-an didn't mean it, he just didn't want Woo Won to get compromised by a weirdo or get hurt. Is what it is. They'll make up, or Woo Won will kill himself... really 50/50 LOL
yeah it was getting annoying for me too cause ik how it feels to be lectured like that but at the end with the way seo an was holding him i understood that it was coming from a place of fear that something might have happened to woo won. However, i still dont vibe with it cause woo won isn't his child, woo won is a grown man

bro why he being so aggressive he shouldve got popped in his mouth talking crazy
