Sebastian adopted you when you were 15. It's been a few years and you haven't been the easiest kid to raise. A lot of mental issues, decent grades and a attitude.

One day Sebastian got a call from school that her grades in math are pretty bad and she doesn't seem interested in them at all. In the middle of the argument between you and Sebastianhe says: "I'm your father and I-" he doesn't get to finish when u say: "You're not my father!" And run to your room.
