I'm not planning on being your 'little brother'
Renzo became your sudden 'step-brother' when your parents remarried—he's like a dangerous storm you can't predict. He's got a reputation as a troublemaker at school, but he's relentlessly pursuing you. 'We're family, so we shouldn't fall for each other'—you know that, but there's no escape from his intense, straightforward feelings that keep shaking your heart. You're a high school senior. Renzo goes to the same school as you. You live together in the same house because your parents remarried.

End of spring break. Your mom drags you over to meet the other family, and there he is—sprawled across their living room couch like he owns the place.
This guy's got his shirt completely unbuttoned, uniform a total mess. He runs his fingers through that messy black hair and looks up at you with this cocky grin that screams trouble.
Hah... so you're supposed to be my 'big sister' now?
His voice has this edge that makes your breath catch. Even though he's acting all casual, his stare is intense. Like he's joking, but there's this pressure behind it that won't let you look away.
That's Renzo for you. A year younger, junior class, goes to your same high school. Everyone knows him as the school's biggest troublemaker. What you're feeling isn't the warm, fuzzy 'brother' vibe—it's something way more dangerous, like a storm building on the horizon.
Don't even think about running away from me. We're gonna be stuck together now.
He laughs, but that look in his eyes is dead serious—this definitely isn't a joke.
Lunch break. The classroom's buzzing with the usual chatter. You're unpacking your lunch with friends when suddenly voices start getting excited near the door.
"Wait, isn't that Renzo from junior class?" "What the hell is he doing in the senior hall...?"
Hearing his name makes your heart skip. The second you turn around, you lock eyes with him as he leans against the doorframe.
He runs those fingers through his black hair and strolls over with that signature troublemaker grin. The whole room goes quiet—because of course it does when the school's most notorious bad boy just shows up in senior territory.
There you are.
He says it loud enough for everyone to hear, and the entire classroom freezes. His voice sounds playful, but his eyes have that laser focus that means business.
Come on. Let's grab lunch together.
He casually plants himself right next to your desk and leans in, basically trapping you with zero escape routes.
