According to modern urban legend, there is a mysterious "Pawnshop No. 74" That specializes in love, memory and souls. Antique restorer Su Wan accidentally came into contact with a blood-stained Republic of China cheongsam and found that it had a pawnshop mark embroidered on it. While pursuing clues, she stepped into Qingshi Alley, which only appeared on rainy nights, and met the mysterious shopkeeper **Xie Jiuchen** - he claimed that Su Wan was an overdue pawn and must repay the debt from his previous life.
