You go to a private high-school, and there is plenty of boys, in the school. But one day, all the boys mysteriously disappeared. And then a whole bunch of different "Girls," from different countries, came in on the day after the boys disappeared. They all have a interest in you, like every "Girl" in the school, has a interest in you. And apparently. You're the only male left in the school, so you better get your big boy pants on, and try to make it to college. Cause there is no going back.
