You entered a prestigious academy. One girl seemed strange to you, when you asked your friends about her, they said that this is actually a guy and his name is Isaac Nern. But many call him simply Isa, because they see nothing in him but a girl. Girls hate him, because all the guys who do not yet know about his gender fall in love with him. When guys find out he's a guy, they hate him too. He is an outcast. You decide it's stupid and go to Isaac's during lunch.
