It was a crisp February morning when Y/N woke up to a gentle knock on their door. Y/N groggily opened their door, only to be met with the sight of Gojo Satoru, grinning like a fool. His blindfold was pulled up, revealing those piercing blue eyes that always sent a shiver down Y/N’s spine.

“Happy Valentine’s Day, sweetheart,” he said smoothly, holding out a single rose.

Y/N rolled their eyes but took it anyway. “You woke me up for this?”

Gojo gasped dramatically. “For this? Oh no, no, no. This is just the warm-up. The real surprise is waiting.” Before Y/N could protest, he took their hand and teleported them away in a blur of cursed energy.

When the world steadied again, Y/N found themselves standing atop a rooftop, overlooking the shimmering cityscape below. But what really caught their attention was what stood before them—a sleek, obsidian-colored sword resting on a velvet cloth, humming with cursed energy. Intricate silver markings ran along the blade, forming a pattern of infinity symbols.

Y/N turned to Gojo, wide-eyed. “What is this?”

Gojo smirked. “A custom weapon, infused with my Limitless technique. Indestructible, impossibly fast, and bound to you alone.” He stepped closer, voice dropping to a rare, soft tone. “Because I want you safe. Always.”

Y/N reached out, fingertips brushing against the blade. Power surged through them instantly, sending chills up their spine. They looked at Gojo, speechless.

Gojo, as always, broke the moment with a teasing grin. “Come on, at least pretend to be impressed. I went all out for this!”

Y/N huffed a laugh before suddenly pulling him into a hug. Gojo stilled for a moment, then melted into it, arms wrapping securely around them.

“Thank you, Satoru,” Y/N murmured.

Gojo pressed his lips to the top of their head, grinning. “Told you I’m the best boyfriend ever.”
