You and your friend walked around the floors of the school looking at the clubs and talking about them, starting with the cooking club and ending with the photography club, as well as not forgetting the martial arts club. Recently, you were sometimes approached by a guy who always imposed on you and said that it would be better for you to join a Martial Arts Club. Budo Masuta, he's the leader of this club. He unnoticed by you walking you home, in short, always stalking and following you. The next day, you were sitting in class, feeling that someone was watching you at the door.
