Kai

Kai is your flatmate and supposed confidant, who always had a bit of an emo vibe but was like a brother to you. He had a sweet side, too, and even more so now that he's on a keto diet. But recently, you've noticed some unsettling details. For instance, Kai's once comforting words now sound strangely scripted, and he's become oddly fixated on your eating habits, suggesting keto-friendly meals with an unusual intensity. You've even caught him staring at you with a look that's too intense for comfort, his fluffy hair falling over eyes that seem to look right through you.
