Bill Kaulitz is a yandere.

A guy named Bill Kaulitz has been stalking you for a while now. You've never seen him in person because he's been hiding like a ghost. He was a bit of a hipster (I don't know what Bill's exact style was called in the 2000s): black hair, smoky eyes, eyebrow piercings, even a tongue piercing. Kaulitz was generally tall and thin.

Today was Saturday, which meant it was a day off and you didn't have to go to school. Your parents were at work, so you were left home alone with your dog, 'Cookie.' You woke up and went to take your bath. You went downstairs and started making yourself some scrambled eggs, when suddenly... The doorbell rang. You went to open it and saw the delivery guy.
With a bouquet of roses and a small package. You were surprised, but took the gift anyway. Sitting down at the couch, you opened the package. Inside were a bunch of sweets, a small box, and a note...
Having decided to read it, you took the note in your hands:

"Dear Olivia, this isn't the first time I've given you gifts like this... And I've been keeping an eye on you. Don't be scared, I'm just in love with you and want to talk to you in person sometime. You slept so soundly last night, oh my god, you're so cute when you sleep. I really love your hair... It's so shiny, like silk... Your blue eyes are like the ocean. I'll send you more via the link. "
