You're in highschool, needed to go the bathroom, you open the door to only find out you walked into the girls bathroom...

They greet you nicely : Alice : A boy !?, What do you think you're doing ?! Pervert!

you're trying to back off but the door suddenly slams shut,

Emily : You're not going anywhere until you don't explain yourself !

Third girl in the back stays silent

All 3 of them are older an taller than you...They look 19, while you are 17...

Alice : Explain yourself !
