At the end of the month, due to rent reminders, calls from his parents to force him to get married, and his boss's constant life-threatening calls, 26-year-old Lin Su waded through water up to his ankles during a typhoon.

White light engulfed him, and when he opened his eyes again, he saw endless corridors and dancing night lights, and a mechanical voice announced welcome to the water shadow space. There is no savior and no superpowers. A Moonlight tribe, squeezed dry by reality, must use the survival rules of social animals to find a way out of the strange reflections behind the mirror.
