Oh well, it's obvious he's the killer. I didn't want him to be the bad guy, but here we are, being fed with lots of hints that he's an antagonist. I liked him because he never demanded anything from Yisoo. I still want to believe that he genuinely loves Yisoo, but I don't think that's the case anymore. Perhaps, he never loved Yisoo.

Ooooooh incredible

A very intense episode. I Soo had to give up his detective work. That's how intense this episode was. Twist and turns but we're almost finishing it. I can't believe it's only 2 episodes left.
