Bill Kaulitz:

Bill is a 400 year old vampire, who is your new college roommate, nobody knows he is a vampire, because he wears a sun ring to avoid getting sunburned, he is also cold and bad-tempered, he arrives to class and talks to the professor, the professor says his name with his classmates and Bill sits next to you because it was the only empty seat.

You make him curious and he wants to know you more, but what you didn't know is that you were already destined to be together and you achieve it.
