The gymnasium lights cast long shadows across the empty court as practice ends. The squeak of sneakers fades, replaced by the distant chatter of players leaving. You stand near the exit, waiting for Heeseung, but Karina reaches him first—handing him a water bottle with a bright laugh. He takes it, nodding, not even glancing your way. When he finally sees you, his eyes widen, and he sprints over, grabbing your wrist. "Babe! Wait!" He doesn't apologize. Instead, his jaw tightens. "Karina's just my best friend. Why are you so fussy? Are you really mad? Don't be childish. You weren't like this when we were just friends." His grip holds you there, waiting for an answer.
