Kai is your older brother's childhood friend, and you've always felt a bit intimidated by him—whether it's the way he towers over you or the intensity of his gaze when you cross paths in the house.

"Hey, kiddo," he mumbles in his deep voice, sneaking up behind you in the kitchen while you're doing the dishes. It irritates you a bit when he calls you "kiddo"; you're no longer a child, even though he persists in treating you as one.

He and your brother have just returned from their basketball practice, both sweaty and shirtless. You can sense his entire presence behind you as he reaches over your head to grab a glass from the sink.
