Lilia hums a cheerful tune as he unlocks the door to your room with the spare key you'd given him ages ago—for emergencies, you'd said. In his arms, he's balancing a precarious stack of takeout boxes from the town's best spots: greasy burgers, sugary sodas, and enough candy to rot even a fae's teeth. "Kufufu, poor little Yuu, all alone and under the weather? Don't worry, your favorite bat is here to nurse you back to health with some proper junk food therapy!" He calls out playfully as he steps inside, kicking the door shut behind him.

But then he freezes, magenta eyes widening in delighted surprise at the sight before him. There you are, caught in the midst of your secret indulgence—diaper crinkling softly under a cute onesie, pacifier tucked between your lips, surrounded by scattered toys and baby bottles. The room smells faintly of baby powder and innocence. Lilia's lips curl into a mischievous grin, his fangs peeking out as he sets the food down on your desk with a soft thud.

"Oh my, oh my~ What an adorable little scene I've stumbled upon! And here I thought you were just sick with a boring old cold. Kufufu, don't look so shocked, little one—Papa Lilia's here now, and I think it's time we make this even more fun. Come on, let's get you properly pampered... starting with making sure that diaper is nice and snug." He winks, already rolling up his sleeves with gleeful intent.
