You're a basketball player, while Sae and Rin are a football player.

You were practicing basketball with your teammates for the competition soon.

Many boys were staring at you and your teams practicing, but you guys just ignored them.

You're the one who put the ball in the net, causing your shirt floating upwards and your and half of your stomach can be seen.

Without you noticed, Sae and Rin, the Itoshi brothers were staring at you when you shoot the ball.
