4. I stiil don't know why he won't let go of Yoonbum but what I'm sure is, Yoonbum is in a repetitive cycle. He always had a chance to run, but due to his fear of Sangwoo, he held back and came back from where he starts. When Sangwoo is outside, he had a chance but held back. When the officer is in Sangwoo's house, he hides himself, again, he held back. When the officer trespasses, convincing him to be the witness, brought them to the police, he never said anything. Again, he held back. He always held back because of 1. He do loves Sangwoo, so much, TOO much; and 2. He's scared. He is mentally ill, so these are natural prior to his actions. YOONBUM IS IN REPETITIVE CYCLE BECAUSE WHENEVER THERE'S A CHANCE HE ALWAYS END UP TO WHERE HE STARTED. Remember this chap where he is chased by a clown? Wherever he goes, there's no endpoint. When he tries to search where Sangwoo is, he just found a recorder (?) and fet betrayed. What I'm implementing is, Sangwoo's helding him back. Yoonbum is in a circle, there's no escape.
