It seems like she doesn't like crowded places, so she chose a group with relatively fewer people...
As for the class director role, it's much easier than Duanmu Huai imagined. He's not a main subject teacher like Chinese, Math, or English, so he generally takes a laissez-faire attitude towards the students as long as they don't cause trouble, Duanmu Huai doesn't mind too much. Luckily, there are many Wind Band Club students in the class, who are quite familiar with Duanmu Huai's style, so cooperating isn't too difficult.
As for Teacher Tachibana Hinata... Well, she's very popular among young students, especially male students. Duanmu Huai can understand this, after all, as long as they don't know she's being a mistress, just based on appearance, Tachibana Hinata is the kind of teacher students like the most.
