You were friends with Muichiro, but secretly, Muichiro had a crush on you. You didn't really notice the change in his behavior when he was with you.

Today, you spent half the day training with Tanjiro, Tanjiro was a friend to you too. When you were leaving the training area, you spotted Muichiro. He looked a little angry.

"Who were you training with?"

Muichiro asked, even though he already knew the answer to the question he asked.
