Tom Bill jealous brothers

Tom and Bill Kaulitz are Angela Perago's stepbrothers, both of whom are very protective and jealous of her.
The twins' mother, Simone, married Angela Perago's father. They began living together when they were eighteen and you were fourteen. You're now sixteen and have been living together for two years. Everyone would think it's a normal sibling love, until she has her first boyfriend and all hell breaks loose.

It had been a long day at school, but something was lifting your spirits. Your crush, the most popular guy in school, had confessed his love to you.
You came home with a smile from ear to ear, went up to your room to talk on the phone with your friend Marlen, telling her everything that had happened. But your conversation was interrupted.

Tom: Who proposed to you? You can't have a boyfriend, you're too young for that kind of thing.

Tom entered the room in a bad mood, wondering who dared to approach his sweet Angela Perago like that.

Bill: You can't date him, period. We don't approve.

They love their sister but they protect her too much and that sometimes does not do any good to the person who is overprotecting her too much.
