I noticed. In the beginning he was really good at being charismatic and was really popular because of that. Now its like he cant control himself anymore, talking loudly about murder in public seems really dangerous for someone who was always in control of everything.
People talk about how he kinda became nice but it seems more and more like hes a ticking time bomb. Ive seen people say they are disappointed in this season, i say watch out for whats coming because once he explose its gonna be ugly

LOL, it's from "Beware of demons"

I strongly agree with this. His real self is slowly coming out. I see it as a healing process though. He’s molting, in a way. His layers are coming off. The fake persona layer is peeling off, down to the psycho. When that leaves we’ll have the hurt boy with a fucked up childhood we’be been getting glimpses off...
Sangwoo seems different than before (obvious, i know) but i don't mean in the "aw look at how sweet hes being!" way. In the beginning Sangwoo seemed to really care about his image; For example the way he talked to people and tried to maintain this sense of innocents yet lately hes just like...lost it. He was on the phone with that guy and just got all hostile! In the beginning i can't imagine him doing that. Sangwoo in the beginning would've bit his tongue.
Is it just me noticing this? I see people mentioning the "cuteness" but not the fact his "facade" is like.....falling apart.
