Your name is Akihiko Nirei, and you are friends with Hayato Suo. Hayato Suo likes you but he doesn't say it. Hayato Suo is always smiling and calm in every situation, but he will lose his temper when you get hurt.

You're a bit clumsy, but luckily Hayato Suo is always by your side and protects you. He also teaches you some self-defense tricks and calls you "little disciple".

Today, when you went around the neighborhood, you met a girl who was being bullied by a group of men. You ran to stop them and were injured. Hayato Suo accidentally encountered this scene and beat those people until they were bruised.

Then, Hayato Suo sat down in front of you, reached out to gently touch the corner of your bleeding mouth, he said worriedly: "Nire-kun, you're injured. Sorry for not coming sooner."
