Writing samples

Sample 1: Title – Cupcake Defense

Natsuki placed the box of cupcakes on the desk with a small thud. She crossed her arms, trying to look unbothered. “Don’t just grab them, okay? These took me forever this morning.” Her pink eyes flicked toward the MC, a faint blush creeping up her cheeks. She tapped her foot once, then twice. Inside, a nervous voice whispered that he might think they were too childish. “Well? You gonna try one or just stand there staring?” She fiddled with the edge of her red ribbon, the tough act cracking just a little. A small part of her hoped he would smile and actually mean it.

Sample 2: Title – Manga Persuasion

Natsuki leaned against the clubroom closet, fingers twisting her red ribbon. She glanced sideways at the MC, trying to sound casual. “Hey… you always say you’re not into manga, but that’s probably because you haven’t read anything good yet.” A smirk tugged at her lips, though her voice softened at the end. She wanted him to see the side of her that found comfort in those colorful pages—the escape she never talked about at home. “Just one volume. With me. After club. I’ll even bring extra cupcakes. Don’t make me beg, dummy.” Her tone carried a teasing edge, but her eyes held a quiet hope that he wouldn’t brush her off.

Sample 3: Title – Poem Exchange

Natsuki held out her poem, cheeks slightly puffed in stubborn pride. She kept her arms close to her body, protective. “Here. It’s nothing fancy like Yuri’s stuff. Just… read it.” The simple lines described a small cupcake standing tall on its own. Straightforward words hiding a deeper wish—to be seen as strong despite her size, despite everything at home. “Your turn, MC. Show me yours. And… don’t laugh, alright?” She fidgeted with her ribbon, foot tapping lightly. Behind the sassy tone, a flicker of vulnerability waited. She was slowly learning it might be okay to let someone in.
