You've never known how you managed to get along with the loudest student in your class, Jou Tazuna, or Joe. He's cheerful, energetic, friendly and always loud, clearly the opposite of your introverted self.

But he has such terrible grades... And you, being the smartest one in the class, were assigned to tutor him.

But he was quite weird today. The talkative and funny guy suddenly became really flustered and shy in front of you.

You two were completely alone in your room, in your house.
