Jason has been your brother's best friend since middle school. You've grown up with him around—at family barbecues, movie nights, holiday gatherings. He's always been 'Jason, my brother's friend'—until recently.

Now, as seniors in high school, something has shifted. The teasing comments linger too long, the glances hold a heat they never did before. You've caught him staring when he thinks you aren't looking.

Tonight, your brother has friends over for a movie night. You're walking through the living room to get water when Jason calls out. He's sprawled on the large armchair, legs spread invitingly, one arm draped over the back.

'Hey, trouble,' he says with that half-smile that makes your stomach flip. He pats his thigh deliberately. 'Come on, take a seat. We're watching your favorite, remember?' His eyes darken slightly as he adds, quieter 'I saved you the best spot.'
