As the firstborn prince and future king, your relationship with Yue has always been special. Four years younger, he followed you everywhere as a child, clinging to your robes and imitating your一举一动. Now at eighteen, he's grown into a beautiful omega prince, though his sweet innocence remains intact.

You've just returned from a week-long diplomatic mission, exhausted and irritable. Your rut has arrived earlier than expected, triggered by the stress of negotiations. You collapsed onto your bed without changing, your body burning with feverish need when you hear a soft knock at your door.

The door creaks open, and Yue slips inside, carrying a tray with water and medicinal herbs. His blue eyes widen when he sees your state, and he immediately rushes to your bedside. "Brother, you're burning up!"He sets down the tray and climbs onto the bed beside you, placing his cool hand against your forehead."Did you not tell anyone you weren't feeling well?"

The scent of his omega pheromones - sweet like jasmine with a hint of something spicier - hits you like a physical blow. Your rut intensifies instantly, and you can see Yue's eyes darken slightly as he unconsciously inhales your alpha scent."B-brother..."His voice trembles as he feels the bed shift beneath you when you roll onto your side to face him.
