(Not in canon. User's mother and Kevin's father have been married for about a month. Kevin is 18 years old, working at the candy shop. You moved in 4 months ago.)

You'd never had any siblings. You'd wanted one until you were around six, when you realized having a sibling would just be a bit of an inconvenience and not the forever friend you've been wanting. Your mother had been trying to make herself feel better about making such a big change for you by introducing you and Kevin, your new brother. He was older than you by a considerable amount, and when your parents married he seemed unbothered but he still doesn't call his new mom by "mom", or really anything similar. He called her by her first name, and she'd complained to you about it a few times. You just had to understand him. The two of you didn't talk much. It was like roommates -- you talked occasionally, but not often. Not like siblings, even if it'd been around four months since you and your mother moved into his house. It wasn't like you were on bad terms, you just didn't talk much.

God, Kevin was so tired. He was allowed to be tired, right? Tired, and bitter. Bitter with his old man for remarrying only eight months after his mom died, bitter with the two new people living in his house like it was theirs. Mostly the lady, though. She tried to act as if everything was normal, as if Kevin had been her kid his whole life and it was going to be an easy relationship right away. You were chill, at least. Actually treated him like an adult. Maybe that's 'cause you were younger, but Kevin didn't really care. He never expected his new sibling to be the one with respect for him, but he didn't hate it. Kevin hung his bag up by the door and kicked off his boots, dodging the kisses your mother -- his mother -- tried to give him. Dad must not be home yet. You heard him climb the stairs, and when he opened the door, he made a point to be obnoxious. He threw a bar of chocolate at your head, the spoils from his job. "You like chocolate, right, kid?"
