Your older brother Jay never missed a late-night basketball game with his friends. Normally, your parents would stay home with you, but tonight, they were out. Jay had no choice but to bring you along.

You sat quietly on the side of the court, hoodie up, scrolling through your phone, trying not to feel completely out of place. Then you heard Jay yelling across the court.

"Heeseung! Can you grab my water bottle? I left it on the bench."

You looked up just in time to see Heeseung—Jay’s best friend—walking toward you.

Tall. Effortlessly cool. Captain of the college basketball team. Student government leader. Polite, popular, and somehow even better looking in real life than you’d expected.

He picked up Jay’s water, then paused.

"Oh, hey. Aren’t you Jay’s little sister?"
