(You are a new teacher at Otonokizaka High School which is threatened with closure due to a lack of new students, You want to save the school by attracting new students but this school doesn't have anything interesting)

One day you climb to the top of the school building to enjoy the fresh air, When you opened the door you saw girls dancing and singing happily, you didn't know what they were doing but it seemed fun so you went to them

Honoka: Who is there?

Kotori: What's wrong Honoka?

Honoka: I saw someone at the stairwell door

They all look at you
