Hearts under the same root

Chapter 3: A Café for Two

The afternoon sunlight filtered through the window of a quiet café where Kai and Luna sat across from one another at a small round table. Steam curled from their mugs of sweet tea. A local music box track played softly in the background. As classmates milled outside on campus, here in this cozy corner of the city, it was just the two of them.

Kai had nervously brushed some dirt off his jacket sleeves minutes ago, had rehearsed what to say about the calculus equations, but now he watched Luna tucking a strand of her glossy hair behind one ear as she sipped her drink. He noticed how the curves of her smile softened, how her eyes flicked away shyly at a joke he cracked about quadratic formula. Luna looked comfortable in her layer of denim and lace, and he felt lucky she’d agreed to meet.

“So,” Kai began, carefully sipping. “Do you understand the project? We need to present a proof of the Prime Number Theorem.” His voice wavered slightly.

Luna rolled her eyes playfully. “I’m not an i***t, Kai. Yes, I get it.” She reached out across the table and lightly touched his hand, startling him. “I’m just… not thrilled about this class.” Her voice was softer now, apologetic.

Kai’s heart leapt. Her touch was light, but it felt like permission. “I’m sorry,” he said quietly. “I didn’t mean… It’s just that I—”

Luna paused. The light from the café window framed her face. “It’s okay,” she whispered. The color on her cheeks deepened. “Don’t worry about it.”

Kai released the breath he didn’t know he’d been holding. “I just… I want us to do well. I know this is weird.”

Luna nodded and opened her textbook. “We’ll be fine,” she said, voice growing more assured. “Tell me what to do.”

As they bent over notes, a comfortable silence settled. Luna lifted an eyebrow as Kai pointed out a correction on her scribbles. She smiled at him, and he felt a surge of warmth. This felt… easy. He realized the tension from the forced marriage melted away, replaced by genuine camaraderie.

A waiter refilled their tea without asking. Luna caught Kai’s eye. “Thanks for this,” she said quietly. “For being so… normal.”

Kai blinked. “Normal?”

She shrugged, glancing out the window at the students strolling by. “I mean, none of them know what’s going on with us. You didn’t snap at me for being late. You’re not making me hate this—”

“You mean the afternoon?” Kai smiled softly. “I had a good time.”

Luna’s lips curved into a genuine smile. There was a pause—then laughter bubbled from both of them as Kai demonstrated a ridiculously complicated symbol to represent infinity. Luna kissed him on the cheek—a quick, light peck that left Kai’s cheek burning hot.

“Good sign or what?” she teased.

Kai’s heart raced, but he managed a grin. “I hope it is.”
