To raise money for her grandmother's medical expenses, female college student Su Wan was working part-time at a pet hospital. Because her eyes were similar to "Snowball," the dog of wealthy young man Lu Shenzhou, she was hired as a "living pet" with a monthly salary of 100,000 yuan. Lu Chenzhou asked her to imitate everything about Xueqiu, from barking to wearing a collar. Su Wan gradually discovered in the luxurious cage that Xueqiu's death was no accident - Lu Chenzhou's mother's recording, the deformed "young master" wearing an urn, and the strange green light in the underground laboratory. Layers of conspiracies involved her in the Lu family's twisted past. When she broke into the abyss with the USB drive in hand, she was shocked to realize that she was not only a substitute, but also the key to awaken the sleeping secrets, and those eyes that resembled snowballs were leading her to the ultimate game of life and death. This is a manipulation in the name of love, a cruel transaction between soul and survival. When the ice pick of truth pierces the illusion, can Su Wan tear open the dark curtain shrouding the Lu family in the strangulation of conspiracy?
