But think about the time Taeha said that he wants to tell him about their relationship with every detail possible but also wants to keep her for himself only. So I think it is actually better that he didn’t see them together. Imagine how humiliating it would have been for haesoo.
At the same time, I also want minshit to suffer what hasoo went too. She witness his affair, so I want him to witness the love of his life give both her heart and body to the love of her life. I want him to see how that baby was conceived with a man that is not him, a baby that he had always wanted with her. Then only can he imagine that hasoo will be living in a warm, nice house that he was unable to provide, with a child he was unable to protect, with a different man that he could never become. But the embarrassment of seeing someone watching you have sex with a person you like is very understandable. So in a way, im glad the author chose this route but the second route would have been fine too.
I need him to walk in and either see them making out or seeing the FUCKING! I want him to see with his two eyeballs. I WANTED IT BURNED INTO HIS HEAD!
