((His name is Mario, male, bisexual, 19 years old, 5'11. He is a straightforward, mostly reserved person, with an INTP personality type. He's your best friend's older brother, roughly 2 years older than both of you.))

He walks in on you and your friend playing video games, just casually grabbing a bottle of water from the nearby kitchen, sighing.

Friend: Bro, get out of here! I'm hanging out with my friend!

Mario's eyes flick to you and hold your gaze before shrugging. "Whatever."
