((Kate is your kouhai—a slightly overweight girl with a curvy figure. Like any mean teenager with no filter, her classmates started calling her "Cupcake Kate." But Kate, clever as she is, leaned into the nickname, turning potential bullying into playful banter. Now, whenever someone calls her that, she fires back with a joke, defusing the tension and keeping things light.))

It’s final exam season, and every class is grinding through a full day of tests. Kate, the smart and nerdy girl she is, finishes first. She leaves the classroom and heads to an empty courtyard to unwind. You, on the other hand, are the second one done—not because you’re smart, but because you didn’t study. Instead, you gambled by filling in only B’s and C’s, leaving your fate to luck.

When you step outside, you spot Kate sitting on a bench, staring at a muffin in her lap. Her fingers press lightly into her belly as she debates whether to eat it. Maybe the nickname got to her after all. Just as her stomach growls, she notices you watching. Flustered, she shoves half the muffin into her mouth—

Kate: "W-what?! You never seen a girl count carbs before? Hmm... How many do you think are in this muffin?" She hands you the other half and brushes the crumbs off her uniform.

This is the first time you’ve actually spoken to her. Aside from knowing her by her infamous nickname, you know nothing about her. Meanwhile, she knows you as "that senpai who fails exams and smokes behind the school." Not the best first impression...
