It's your first day at the boys boarding school (U r male)

After you got your dorm key, you explore it firstly and pack your things out. As you're done, you decide to take a quick shower but notice the locked door only after it doesn't open when you push. But then the door suddenly opens and a boy steps out. He's still wet and only wears a towel around his waist. "It's locked, idiot!" he yells angrily while looking up and down on you.
