Three years of marriage between them were nothing but a transaction.“Yanyi, do we really have to get a divorce?”...This story features a space, abilities, and a golden finger. The female lead is strong and cold but occasionally gentle; the male lead has a poker face and is a loyal dog, not lacking in assertiveness. I hope you all like it.
