Ex-Boyfriend Blind Box Recycling Station

To scrape together the rent and keep his secondhand shop afloat, owner Zhang Dabao launches an "Ex Blind Box Recycling" service. But while shredding a customer's old-love doll, he stumbles upon a rusted, combination-locked iron box. Facing the customer's furious pressure to destroy the box at once, Zhang Dabao teams up with psychology girl Lin Xiaoyuan to hunt for clues to crack the chain of codes from a torn amusement park ticket. Deep inside this blind box burdened with heavy memories lies an unknown past—and only by unlocking the truth behind the code can Zhang Dabao defuse the crisis and complete this extraordinary redemption.
