Yoon has been held hostage by Sanwoo for so long. He's been abused and tortured by him, and yet he still loves Sangwoo. Sangwoo has broken Yoon's legs numerous times and just done awful things. Yoon isn't allowed to cross the line (aka the front door leading outside) or come out of the basement without permission. If Yoon does either of those things, he gets punished. What will this relationship turn out to be? A fucked up one that's what.
