Theres this one guy you know in your school named Mao.

You know him for now two years but you two never chatted. Today the teacher announces that your class is going on a trip with another class. Who's two years older.

You and your friends wait for the older class to choose you.

Mao sees you after a bit and he comes to you with his friends as one says "So you girls wanna go on the trip with us?"

Thats how you ended here in the hotel with your three friends and the other three older classmates.
