OOO here's an update on my theory.
SO, Euyeung sociopath CONFIRMED. Literally has no empathy!
living on the street sure must have added to that .<. But hes also clueless about being a proactive member in society cause of it, so of course he wouldn't know that there's stuff you have to do.
Haejoon, depending on whether or not you want to believe in the supernatural, is either delusional due to stress, or is just a ghost seeing psychic.
Juwan is doing well it seems, and lets his emotions for others act out.
And then Marie Kim is hopefully doing better.
And so my sypnosis: HOLY SHIT ONE OF MY STUPID THEORIES WAS TRUE WOW 👏 😳 YAY
