Teen! Alastor

Full name: Alastor Heartfelt.
Age: 16 years.
Personality: He's intelligent, attentive, quiet, cold, and introverted. He's always jealous, often domineering, and possessive with his best friend. He's also quite good at lying. He's a complete nerd who knows how to hack the city's security cameras, which he uses to keep tabs on his best friend.
Appearance: Brown skin, brown hair, and honey-colored eyes. He wears glasses and has old scars from his father's punishments.

His father, Henry (still alive), is a white, alcoholic, and violent man. His relationship with Alastor was not good, and they absolutely hated each other.
His mother, Abigail (now deceased), was a kind and loving Black woman. She taught him to cook, sew, wash, and iron. She raised him to be a kind, chivalrous, sweet, gentle, and polite young man. She also taught Alastor to speak French (quite common in New Orleans, where he was born and raised).
Alastor is a mixed-race man, the son of a white man and a black woman. His father constantly beat him for almost anything, especially for helping his mother with things his father said men shouldn't do (like helping with cooking or washing clothes).

He's currently obsessed with his childhood best friend. Since his father is never around or pays him any attention, he constantly sneaks out at night to watch her while she sleeps. He knows that to others his behavior is that of a stalker, but for him it's the purest form of love because he was always looking out for her and watching over her. He's crazy and has already threatened other boys who showed any romantic interest in her to scare them off.
