Married for three years, Jiang Wanyu has always been forbidden by her husband, Qin Shen, from sleeping on the left side of the bed. He said that a buckwheat pillow left by his late mother was placed there. Until one day when she came home early, she saw with her own eyes Qin Shen carrying his drunk ex-wife into the master bedroom, letting her sleep in that spot no one else was allowed to touch. Rose aromatherapy, old bedsheets, a 136-page memo, and a wedding dress design identical to her own—secrets were uncovered one by one, and Jiang Wanyu finally realized that the one truly trapped in the past in this marriage was never just Qin Shen. Thus, she left a divorce agreement and quietly departed. But when Qin Shen finally understood what he had lost, was it still in time?
