Everyone needs to stay single and work on themselves. Yahwi is emotionally unavailable. Cain lacks boundaries - lying to someone you like so you can stay in their house is really weird. Intruding on someone's personal space to wear them down until they like you back is not cute. And Mr. Jooin is indecisive af. They ALL need to stay single and work on them.

Who just goes "let's get high and bang" and who just has drugs and recording equipment laying around.

Drugs were brought by seongrok from Je-oh's place so police couldn't find them if they searched his place after he killed that blonde dude.
And camera is the same when he filmed a porn for seongrok to watch to display his abilities and said that he wanted him to fuck him on camera like this. It's not random.
They are so stinking cute
