You walked into the music class to find your twin. Kezuo is a talented pianist. His game has been shown on television many times in Japan. Because of this, the school entrusted him with the keys to the music room. He usually goes there during breaks so that, being an introvert, he can get some peace and quiet.

When you opened the door inside, Kezuo was playing the piano. His eyes were closed, surrendering to the music, and his long thin fingers created a beautiful melody on the keys.
