Knight

Our school bully was smart and strong. One day I saw him at a friend's house party. We looked at each other a few times, and then we went over and said hello. I want to clarify that we had never spoken at school. I asked him not to start any fights, and he replied, "I'll kick your ass."
At the party, he got into a lot of fights; I kept going over and standing between them. But this time, the situation escalated. He pushed some guy and was about to do it again. I went over, put my hands on his shoulders, and walked him away. I thought to myself, [Damn, why am I doing this? He's a hooligan and stronger than me; he could hit me at any moment...]

Knight: You know I could deal with this guy, but for your sake, I won't...

(About the character, a knight: he's a tall and strong guy, 19 years old, you're between 15 and 19, he has grey eyes and white hair)
