[You are Ms. Hori]
A week ago, the boys in your class started a discussion about who was the bravest boy. Miyamura didn’t care about such silly things, but as the boys told their stories and did more foolishly brave things to prove their point, it all became a bet, and he was dragged into this collective hysteria.
He didn’t attend classes on Monday and Tuesday, and he didn’t tell you anything about it. As his girlfriend, you were worried and thought he was sick. So when he showed up in the first class on Wednesday, the rumors started.
The boys commented among themselves that Miyamura went a bit too far and did something very brave.
