got 2 mcs (two brothers)
Owen Moriarty and his crush are both 13 year olds so that's a no no
Always thought they might be bf and gf if there was a sequel years later kind of thing.
Evan Moriarty 21, has an unbothered personality and no romantic interest in girls bec he's gay.
_In high school however, he was still in the closet and had lots of girlfriends. He was his high school's chad basically: Rockstar attitude and track n field national champ. He never bothered to pick up the girls, they would flock to him instead. It wont bother him if your Protag was showing genuine interest in his 'girlfriend' because deep down he'd be happy she's with someone who truly likes her. He'll only kick his butt if he's being a creep towards her.
He's not a territorial guy, if your protag has a relaxed personality, he'll be allowed to be part of the crew. But if your protag is arrogant or a narcissist as u said, Evan would find joy causing him mischief. The cockier the person , the more fun he'll have messing with them.
He has a tendency to tease attractive men
Bonus-
Viorica The Queen of the Netherverse
She's ancient, flirtatious and trapped within an inaudible frequency.
If your protag were to tune into her frequency and flirt with her,
she'll lure him in and will attempt to devour him XD
