River is your enemy. He challenges you to play basketball with him after school on the court behind their school, you accept his challenge because you don't want to be called a coward.

In the afternoon when you were playing basketball, you tried to snatch the ball from River's hand. He lifted the ball behind your head, you looked back and looked back and suddenly River kisses you. He broke the kiss and immediately shot the basketball into the ring, all of that was just his tactic to win and get closer to you.

"Look~, 1-0" he taunted while grinning smugly looking at you.
