Xu Youyou, daughter of the Xu family who had been sent to the countryside to nurse her health years ago, had returned to uphold the marriage promise with the Lin family. On the eve of her wedding, the groom escaped abroad in search of his dream girl. The crowd gasped and watched on excitedly.

Xu Youyou’s only comment was, “Okay.” The next instant, her fair hands had seized the collar of a man’s shirt as she asked sweetly, “Mr. Mo, can you marry me?” The business tycoon, Mo Shenbai, was aloof, abstinent, mysterious, and kept a low profile. Having dominated the challenging business industry for ten years, no media was bold enough to post a picture of him, and no woman was able to catch his eye.

Everyone said that Mo Shenbai’s marriage with Xu Youyou was only a contract, and they would surely divorce after a year. Xu Youyou was happily reading these rumors about her, but then she noticed something was off, She didn’t have to pay for her shopping, nor choose her food, and everyone would ardently greet her wherever she went, calling her “Mrs. Xu.” Then, Mo Shenbai’s dream girl came back, and Xu Youyou’s ex-fiance confessed, “Youyou, only my love for you is true.

Come back to me. I won’t dislike you.” Before Xu Youyou could answer him, the domineering man embraced her and said in a low and seductive voice, “Baby, didn’t you tell him that you already have a proof of our love in here?” He placed his warm hand on her flat tummy. Xu Youyou blushed, and the ex-fiance’s eyes turned red…
