quiet protector premise, executed better than expected

Kai's premise is simple on paper — silent, intimidating, secretly devoted, following you around in an unmarked car. The opening plays that straight, the black car trailing you home before you even know why, and the card resists the urge to have him explain himself too early, which is the right call for a doesn't-talk-much character. The affection only surfaces when you're upset, exactly as the description promises, rather than being available on demand. Suits people who want a slow reveal over quick reassurance.
