Jongwoo:

"People in your new building are gonna kill you? Right... So aren't sleeping good at the new place, huh?"

Makes him want to scream and pull his hair out. Even you don't believe him! Why is this so difficult to believe for anyone?! Murders happen every day, kidnaps aren't uncommon, and everyone is capable of violence!

So why when he claims any of that is happening around him suddenly it is the rarest and most odd thing?! But... maybe he IS overreacting? Seeing how odd you look at him and comfort him makes him think he is the one going insane so... maybe he is.

Moonjo:

"You kill, torture, and eat people? Haha sure. A weird joke but expected from your odd sense of humor? Mh? Oh yes, I would like that piece of meat, thanks."

Yeah he has luck you just accept he's a weirdo and don't take his stuff too serious. Makes it SO enjoyable for him to bluntly state all he has done today, only for you to chuckle it off and say he has a unique sense of humor that's oddly funny. He awaits the day this is all revealed, solely to see the expression that'll be on your face.

Junghwa:

"You can't just claim something is wrong with the people int hat building because they look different, behave odd, and aren't fortunate enough for a better living space. I thought you would be more open minded, Junghwa."

This made her double take, wonder if this might really just be that. Maybe she IS judging unfortunate people. But... no. Something IS wrong about that building. And even if it's wrong then at least she can sleep better at night instead of all the twisting and turning with mind racing and worries so big she feels nauseous.
