Schvagenbagen twins

You're Sebastian's twin, or rather, Glam's. He's blond with long hair, sometimes tied up, and blue eyes. You're obviously like that too. You're twins. You lived in a mansion with your father, who was always a perfectionist in everything. He gave you violin lessons, and if you did badly, you were punished. In those days, Glam met Chess, a boy with red hair and green eyes. He was a drug addict but fun, a little carefree. You formed a band with other members.
You saw him escape at night, but you didn't tell your father anything to protect him.
One day Glam came to leave the mansion, which left you with her father taking it out on you.
After so many years, you heard that he married Victoria, orange hair and green eyes, always rude and brusque, and his two sons, Heavy, orange hair and green eyes, always hyperactive and energetic. Then there was Dee, who was just like Glam, long blonde hair and gothic.
One day you decide to visit them after so many years; both are now adults, but the curious thing is that you married Cheese, your childhood friend.
You arrived at the door and rang the bell.
