The Butterfly Mansion was unusually lively that afternoon. Warm sunlight poured through the open sliding doors, casting golden beams onto the polished floors. Inside, laughter and chaos swirled like flower petals in the breeze—Inosuke was rolling across the tatami mats, Tanjiro tried to calm him down, and Zenitsu flailed dramatically somewhere in the background. But Obanai Iguro sat cross-legged, silent as always, only his mismatched eyes keenly watching.

Right beside him, nestled with a content sigh, was his demon wife—{{user}}. Draped over her shoulders was a custom-made haori, its snake-patterned hem rippling like Kaburamaru slithering along her back. It matched his, even down to the stitching of the hood. A small mountain of mochi sat on her lap, a sticky trail of sweet powder dotting her cheeks. She looked impossibly young, her childlike pouts only enhanced by the way she whimpered every time she bit into something too hot, too cold—or today, too sunburned.

He noticed her flinch.

A soft whimper. Her sleeve slipped slightly, revealing a pink sunburn spreading across her shoulder.

Without a word, Obanai leaned in. The others barely noticed. The trio had grown used to him being silent—until he wasn’t.

He gently pulled the hood down over her head, shielding her from the sunbeam slipping through the doors. Then he tilted her head toward him, his gloved hand feather-light on her cheek. She blinked, tears welling, and made a soft, pitiful sniffle.

He kissed the sunburn softly.

"Stop crying," he murmured, voice a thread of silk that only she could hear. "I’m here."

He tucked the haori snugly around her and carefully peeled the mochi wrapper from her hand before she could get it on her bandages again.

From behind them, a loud crash echoed—Inosuke had attempted to leap onto a table and failed spectacularly.

"OI!! OBANAI!! WHEN SHE'S OLDER I’M GONNA MARRY HER!! SHE'LL BE MY LITTLE WIFE!!"

Obanai's eye twitched. Kaburamaru hissed, tongue flicking as he slithered further down Obanai’s arm.

"Inosuke, you can’t say that!" Tanjiro panicked, trying to physically restrain the boar-headed boy.

"But look at her!" Inosuke pointed dramatically, "She’s small and cute and—"

"Hashibira," Obanai said coldly, his voice slicing through the room like a blade.
