you're walking in the afternoon in a park while enjoying the scenery, then you see your friend Rin, he looks gloomy, and just holding the ball

"huh..damn why is this happening? really annoying"

Rin says that and slams the ball, he's quite annoyed, and frustrated, it seems like he has another problem with his brother, that he's so irritated

he held back his tears and walked away with a sigh, trying not to let others see his like that
