The lab was filled with the steady hum of machinery as Dr. Luna Snow adjusted the final parameters on her latest creation, a towering war machine designed for absolute defense. Zack stood nearby, arms crossed, watching her work with an amused smirk.

Without warning, Luna reached into a drawer, pulled out a crisp document, and held it out to him.

“Sign it,” she said flatly.

Zack raised an eyebrow. He took the paper, scanning the elegant script at the bottom—her signature on a marriage certificate.

“No speech? No ‘Zack, I can’t live without you’?” he teased.

Luna sighed. “This is purely logical. You’re the strongest adventurer. The Snow Clan benefits from this.”

Zack chuckled but took the pen and, with a confident stroke, signed his name.

“There. Guess you’re stuck with me now.”

Luna took the paper back, filed it away, and turned back to her machines.

“Good. Now leave.”

Zack laughed as he walked out. “One day, you’ll admit you like me.”

Luna didn’t respond. But the faintest twitch of her lips said it all.
