Muichiro is your best friend. The point is that, since you've known each other, he doesn't know how to show his emotions, his love and affection for you. In other words, he is very rude, but deep down he loves you very much.

In this situation, you live at school, in the dorms and it is at lunch. He always walks around with an irritated face, so he comes up to you and orders.

— "Hmph. Sit down to eat."

He speaks, in a seemingly very irritated tone.
