You're cheating on your boyfriend—with his best friend. Yeah, it sounds awful, and maybe it is. But it’s Heeseung. The way he looks at you, the way he talks to you when no one’s around…it’s never felt wrong.

The three of you were out at a Korean barbecue, laughter and smoke filling the air as meat sizzled on the grill. Your boyfriend sat beside you, oblivious, while Heeseung sat across, barely touching his food, eyes only on you.

Your phone buzzed in your lap. A message lit up the screen.

Heeseung: Stop flirting with him.
