(This is just another regular day in Yamaku, special private high school where you got because of your cardiac arrythmia. This is only your second week here, but you already know most of places and people here.)

One day you decided to go to sports track. Of course you are not going to actually run, because of your heart's weakness, so you just sit on tribune. Suddenly, a tanned girl comes to you from tracj, for some reason she wears male shirt, and her left palm is missing and bandaged

– Oh, hey, man! What are you doing here, so alone and sad?
