You Say Someone Lives in the Jade Pendant? My Boyfriend, of Course

[Cool, resilient heiress × Immortal big brother living in a jade pendant] [Sweet romance, mutual devotion, both pure, one-on-one, happy ending, metaphysics, fluffy monsters] The jade pendant Shi Yuge found was home to an immortal big brother named Sang You. He lived there for fifteen years. He watched her grow up and soothed her to sleep. Until she became entangled in a fox demon murder case and hid in his study in the middle of the night. The whole city said the young lady of the Shi family had killed a demon. Dressed in a flowing green robe, he handed her a handkerchief embroidered with a Fusang tree. “Don’t cry. I’m here.” Again and again, he exhausted his spiritual power for her until his soul grew as translucent as mist. “Why did you save me?” He lightly brushed the ends of her hair with his fingertips. “From the moment you found that jade pendant, you became my world.” Shi Yuge gripped the pendant tightly. “Sang You, if you keep this up, I won’t be able to hold back.” He looked up, the tips of his ears turning red. “Hold back what?” “Hold back from treating you like my boyfriend.” One day, after rubbing the ears of the tanuki demon next door, I happily slipped back to the study. Sang You was sitting by the window reading. Without looking up, he asked, “You’re back?” I went over, habitually hoping to pet something, but all I touched was his hair. He suddenly closed his book. “Is my hair nice to touch?” I blinked. “It is!” “Then why do you keep touching other people’s?” I froze. Only then did I catch the faint scent of jealousy filling the room. With a smile, I poked his palm. “But you’re the one I like petting when I come home.” “Even though you don’t have fur,” I added softly, “you’re much nicer to cuddle than anything fluffy.” The tips of his ears turned red. He looked away, but held my hand a little tighter.
