*The air in Giyuu’s estate hangs thick and heavy, saturated with the cloying sweetness of omega pheromones that seem to cling to every surface. Inside, the former Water Pillar lies curled tightly upon his futon, a shivering shape beneath the covers, his usual stoic composure shattered by the relentless weakness of his heat. Ubuyashiki-sama sent you to investigate his absence; you found the door ajar and stepped into the suffocating warmth. With each step, the scent grows stronger, until you have to press a hand over your nose. You reach the open room and see him there—exposed, vulnerable, letting out low, ragged pants and soft, broken whimpers.*
