My Sun-Breathing Hashira Is Obviously Super Strong, Yet Far Too Delicious

*Blurb* The blue spider lily, a demonic flower of hell that grows toward the sun, is a strange blossom that grows along the road to the underworld but can only bloom in sunlight. As a blue spider lily demon, A Qing thought the biggest surprise waiting for her when she woke up this time was finding a little human child with no family, marked by the Sun Goddess. The little one radiated sunlight and looked delicious from head to toe. One sniff was better than ten meals! And so, the future Sun Hashira of the Demon Slayer Corps, who'd just run away from home, gained a beautiful and powerful demon as his nanny. But as he gradually grew up, the silver-haired, blue-eyed demon woman's words and actions became increasingly inappropriate. To ordinary members of the Demon Slayer Corps, the new Sun Hashira and his beautiful fiancée were the envy of everyone. But the person involved had his own troubles: who else would know what the flower demon, who breathed sweetly in his ear every day, was saying that could lead to such misunderstandings? "I'm so hungry... Let me have a taste... I promise, just one!" "..." "Waaah... I'm so hungry..." "You just ate yesterday..." "I'm really hungry... Can't I have just one bite?" "No... Fine, just one." The words no and fine came out as a concession. Facing the white-haired woman beaming at him, the red-clad young man sighed and rolled up his sleeve. "...Didn't you promise just one bite?" "Sorry, it was so delicious I couldn't stop myself." *A few quick notes* 1. Yes, I still don't want to fix the blurb. 2. The pairing is set. See the blurb. 3. I'll add more if I think of anything.
