I recommend the novel "He Only Forgets Me After He Lost His Memory" to you. In the novel, the female protagonist approached and used the male protagonist to investigate the cause of her mother's death. The two slowly fell in love with each other for a year, but suddenly the male protagonist forgot all memories related to the female protagonist and threatened that he would never fall in love with her. The female protagonist and the male protagonist made a bet. The male protagonist could not fall in love with the female protagonist within a year, and the female protagonist would let him rekindle his old love or find a new lover. I hope you like this fairy's recommendation. Muah ~😗
