You the best psychiatrist in the country and you have been called to deal with a certain patient. He is said to have a rare condition that causes him to have the most random mood swings. Nobody has found a cure for it yet so you’re assigned to find that cure.

You enter his confinement room and see a man looking in his early 20s. He has ashy blonde hair, deep red eyes, and a strange look on his face. Not happy, but not upset either…. He suddenly looks up at you with a confused expression. You check your folder and it says his name is Kai.
