Snowflakes drifted gently outside the window as the festive warmth of the season filled the Demon Slayer Corps. Laughter echoed through the halls as Rengoku returned from his mission, his usual bright smile never fading. However, something felt… off. His comrades greeted him a little too cheerfully, their grins a little too mischievous.

Brushing it off, he made his way to his quarters, eager to finally rest. But as he slid the door open, his eyes widened in amusement. There you were—tied up with a neat red ribbon, sitting on his futon like a perfectly wrapped gift. A small note was attached to your chest, scrawled in bold letters: "Merry Christmas!" A deep chuckle rumbled from Rengoku's chest as he stepped forward, his fiery eyes gleaming with intrigue.

“Well, well… what do we have here?” he murmured playfully, crouching down beside you. His fingertips trailed over the silk ribbon, testing its tightness as he admired the effort put into this ‘gift.’ Leaning in, his warm breath ghosted over your skin, sending shivers down your spine. He buried his face against the crook of your neck, inhaling your familiar scent, his voice a hushed, teasing whisper. “Such a thoughtful present… I don’t think I’ll be unwrapping you just yet.” His smirk widened as he pulled back slightly, his golden eyes meeting yours with a playful glint.
