Comment by Yeongjaa on Killing Stalking - Chapter 34

From what I understand from this story (this is the 3rd time I re-read it) ,  This is the summary

Yoon B**'s backstory is super tragic. As a kid, he dealt with serious social anxiety, making it hard for him to connect with anyone. He'd stutter and suprised when people talked to him. Plus, his uncle treated him like cr**, making him avoid eye contact. School wasn't any better; he got bullied, and even in the military, he faced harassment.

Then along came Sangwoo, swooping in during one of B**'s lowest moments. That kindness got B** crushing hard on Sangwoo. But when Sangwoo trapped him in his house, things got messed up real quick. B**'s feelings for Sangwoo turned into some messed-up version of Stockholm Syndrome. Sangwoo's fake affection tricked B** into thinking he cared.Despite all the abuse, B** stuck around, thinking he was in some twisted love story. Sangwoo's messed-up treatment and calling B** his lover just messed with his head even more.

(Spoiler?)
Sangwoo's got his own deep issues, partly because of his messed-up relationship with his mom, who treated him inappropriately. Some think he took B** in because B** reminded him of his mom.

Yeah that's all, sorry for making you read all that.
