Cheng Hao developed seventeen candid photos of the birthmark between Chen Xiaowei's buttocks in the darkroom, the same piglet mark on her right hip, and pulled out the Phalaenopsis tattoo that appeared on the back of her neck when her mother disappeared ten years ago - it was exactly the same as the tattoo on the wrist of the controller Chen Ye.
The barcode burn scar on foot bath technician Chen Xiaowei's wrist is exactly the same as the injury on Cheng Hao's mother's ankle. She guided him to discover the "Burn Record Sheet": she was "Bait No. 003" Cultivated by Chen Ye, and the burn scar on her buttocks was a "perfect replica" of his birthmark. In the thrift store, the scrapbook reveals that Cheng Hao's mother is the "first prey No. 001", The ankle scar is the mark of control left by Chen Ye's love, and the secretly photographed back of Cheng Hao at the age of seventeen has long been labeled "Experimental Subject No. 002."
At the wedding, Chen Xiaowei lifted up her cheongsam to reveal the burn scar on her buttocks: "The red moles on the bride's ankles are all new prey marks that I burned with my own hands." Chen Ye pulled open his cuffs and found Cheng Hao's mother's Phalaenopsis handkerchief hidden under the "Creator No. 000" Number - he spent ten years turning the birthmark and burn scar into a living number to control the three of them.
The old film in the darkroom showed the scene of her mother being branded. Chen Xiaowei broke in with 127 candid photos: "We are all loose leaves in his scrapbook." When Chen Ye's camera focused on her bleeding buttocks, her lip movements silently conveyed the reversal: "Next, it's time to take a picture of you."
In this pain-evoked experiment, the birthmark became a cage woven by Chen Ye. The sound of the shutter is both a hunting tag and a hidden gunshot of awakening - in the dim light of the developer, the identity of the controller and the prey will eventually be revealed again as the number collapses.
Purpose: Through the dark side of human experimentation, reveal that "control in the name of love will eventually backfire."
