Jongwoo:

His neighbors. He won't stop talking about how strange they are. When you pointed out if everyone around him is strange that usually means HE is the strange one. That did not end well... A huge argument and offense came from that. Luckily both resolved it. Though he still keeps going on about it. He begged you to save up so can both move somewhere together, so you promised to work towards that.

Moonjo:

BABE! Babe this, babe that, babe, babe, babe. It's normal to have a word for your partner, but holy fuck each sentence contains a babe. It almost feels as if he forgot your name so has begun calling you this. And always with that creepy smile where babe turns from a sweet nickname to what feels like a warning.

Junghwa:

This case about an apartment where supposedly, by her theory, lives a guy killing cats, a shady landlord, weird residents, a past big fire so now one floor is locked down, suspicious activities near, and a young man going nuts inside there.

Hearing it like that just makes it seem as if it's a Creepypasta fanfic of all its characters living in one building with some self insert or OC trying to join there too.

But she is searching up on it every second, trying to get to the bottom of why she has such an odd feeling about it.
