Lol I just realised after reading the prologue that the dead body was just looting my bad
But my theory about Jinwoo stays
That is possible too but what if Guwon did killed his dad and that is why jinwoo tried to kill him. And the reason Guwon vomit just after their kiss is that he know that Jineoo might tried to poison him. Like someone might already tried to poison him considering they might want to take revenge
His dad is the silhouette hovering over Teach. It "flashes" from the figure hovering over him, to showing his dad's smiling face. The dad tried attacking Teach, and he had to fight back. He killed his dad and blocked the trauma. So I think he still remembers the good about his dad and not the danger. I can't remember the chapter, but it was hinting his mom's health got worse, and maybe the dad had something to do with it, but Teach blocked it out.
I hope not becus shit is abt to go down
I have a wild theory about Jinwoo.
What if he accidentally 'killed' his dad? Imagine he has these intense nightmares, and when he wakes up, he's still in 'killing mode.' until he realises it.
In the first chapter, we see someone was killed near him, and he wakes up bloody or injured, right? Maybe that wasn't just a random incident. What if it was his dad(or maybe not) , and Guwon had to intervene to stop Jinwoo?(since he was in killing mode) Guwon might have used his 'rock muscle' to subdue him, which would explain why Jinwoo woke up feeling fuzzy and disoriented, like he was asking, 'What just happened?'
Maybe he has ptsd or it's his defense mechanism
