Honestly, all the characters are shady at this point

I think that Cicero is the killer, Baron might know that Jonathan is the final kill and Kister has some sort of deal with Cicero for why he took the fall for the crime and is pretending to be a psychopath (I'm kinda iffy about all this psychology stuff, but if we go by manhwa logic).

Johnathan and Baron probably knew Kister at some point in the past with the dreams, Robert and the blue-haired best friend are stray pieces that could really affect the plot but aren't a part of the killer... triangle? Square? Polygon? Anyways, I'm worried about what damage those two could do because Robert is a nutcase and blue is starting to suspect Cicero but he looks like he might target that feeling towards our boy. Also, Robben hiding things from the police has me pretty suspicious but idk how he'll fit into this whole thing.

Well, the slow burn romance is at least going well (づ￣ ³￣)づ
