@ahjuicys.washboardabs But, I think I didn't just like your comment... I LIKED YOU! (And plays the song "WHITE TEE" and puts a rose in my mouth *The trend never dies*). 
Just kidding.......haha...no, I'm not kidding, I've fallen for you.
(sorry, I guess this is the curse of EMOTIONAL DROUGHT that's afflicting me).

@Dancing pumpkin No...it's fine.

@Dancing pumpkin Yes, I know she will die...but not only her, actually he kills people who break laws (city laws)*Rules or laws*  and the doctor broke the law "not to leave the city" or maybe "return to that place", but he only killed the doctor and left teach, but teach was scared and thought that Guwon would kill him, because he also broke the law. 
Well... I'm glad teach is okay and Guwon didn't kill him, but that's why teach is terrified of him and refused to have s** with him this chapter , because after that incident he developed trauma, and in the truck when Guwon kissed him,teach throw up...*Sorry...this is a little sad...and kind of disgusting* (I'm not sure, but I remember him throwing up and getting sick and feeling nauseous every time Guwon kissed him or did something else after that incident, and also because he believed that Guwon was the one who killed his father, so this makes him sick). 
DON'T JUDGE, I DON'T HAVE ANY NEGATIVE FEELINGS AGAINST THEM, AND I'M USED TO READ BLACK FLAGS LIKE THIS MANHWA-(I LIKED IT A LITTLE BEFORE THIS DESTRUCTION,WHEN IT WAS NICE AT FIRST, *MAYBE A LITTLE NICE*). 
Thanks,anyway... I just wanted to clarify my OPINION. 

@Dancing pumpkin Well, maybe they really are afraid of him, which is why the girl was trying to kill him at first. But I feel like the TEACH is traumatized by this. He always dreams about being the reason for their destruction or death. It seems like GUWON really cares about him because he sees him as a husband or something, but I feel like there's something strange about him. I don't trust him, and I think he has a dark past. His situation is unreliable. Anyway, the doctor was really kind. I can't believe he just died so easily. I saw him as the only one who had mercy and helped people, and he was simply killed. This hurt my feelings. I think everyone he dreams about will die or be killed by Guwon because of Teach, because I remember the doctor appearing in his dream. So he was the beginning. I expect the girl is next. Maybe. I hope not, because in the end, they don't deserve to DIE.

@Dancing pumpkin I already know, but tbh it was a surprise. And btw, do you think no one is focusing on the doctor?.

@Ticcy I know the story, and I understand the chapter, but I ask why this randomness? I mean, the chapter shocked me 1000 times. Every time I was shocked, I was shocked and surprised by the worst. Thank you for the explanation, but I really didn't need it because I understand what happened.
