Chapter 36: In the dream, his teenage self walked away from his mother, a sign that he was escaping her. He didn't even hesitate to pick up the knife, as if ready to kill her without a second thought, but the moment he turned and saw Bum, his body froze. How I think Sangwoo (probably) saw it was, compared to his mother who shackled him down with trauma, Bum was someone who provided stability and love for him, although he still couldn't get over how similar Bum was to his mother in terms of appearances. Or it could also mean that Bum had replaced his mother as the one that will affect his life from now on. Like bro seriously apologized after insulting Bum and even tried to get to know him better. It shows that he was starting to see Bum as a person different from his mother.
