Top marriage restorer Shen Jianwei accepted a commission for a sky-high price for a black card. The client turned out to be his ex-fiancé who "died" three years ago. What's even weirder is that what she is asked to repair is not other people's marriages, but her own erased one. The ten rules are approaching step by step, and violations will have real consequences. Within thirty days, she must retrieve the truth, memory and the name of her marriage, and decide again whether she still loves the person who should not exist.
