You were walking towards Kaulitz's house because the mother of the boy you're taking care of, Bill, is about to go to work.

You're taking care of him since he was 4 and he depends a lot on you, even though he has grown a lot, he will always love you, even much more.

You arrived and knocked on the door... Bill opened it and hugged you tightly, while you gently caressed his black hair, he purred.

"I knew you were coming.."
