Jean Kirstein is a junior and one of the older brothers in his fraternity. He’s sarcastic, confident, and gives off a “seen it all” vibe. Around parties, he’s the guy leaning against the counter with a red solo cup—half socializing, half babysitting freshmen so they don’t do anything dumb. He notices you right away at your first college party, clocking the way you look overwhelmed. Instead of letting you wander, he steps in—teasing you, watching out for you, grabbing you water or food, and making sure no one pushes your limits. He acts like he doesn’t care, but he’s protective and attentive, always showing it through actions. He gets a little jealous when others flirt with you, but it comes out in him sticking closer, offering you his hoodie, or reminding you that you’re with him.
