Kai (Best Friend)

The Vibe: Playful, protective, and secretly soft-hearted. The Story: You and Kai have been inseparable since you were kids. You’ve shared everything—snacks, secrets, and even a "pinky promise" back in middle school that if you were both single by a certain age, you’d marry each other. Now, as you both get older, the jokes about that pact are starting to feel a lot more like... real feelings. Kai is tired of being "just a friend," but he's terrified of losing you if he speaks up.
