i think his father killed his mother ans so Woo killed his father as revenge
wait...pg 45 the woman isn't his mother? Him killing her? idk I'm confused now...lol
no no
from the start he is orphan
the officer who knows Woo said that his parents were killed but the officer who came to investigate doesn't belive it and is suspecting Woo that's why he came to inspect
pg 45 is a flash back.
Sangwoo's parents died when he was 14/15.
I actually think that.... because he sees Yoonbum very similarly to how he saw his mom that flashback was more him seeing himself as his dad killing his mom. Like equating his decision to kill Yoonbum as the same level.
But then again it could be literal and not a metaphor. Its hard to tell whats a hallucination in this story sometimes.
So I'm guessing that Woo killed his mom because she decided to leave him (?) mmmmmm (⊙…⊙ ) (or did he mention a different reason before)
