Then, she discovered that the stranger was actually her ex-fiancé's uncle she met every day!“It's you!” She was so shocked.“Marry me. I'll deal with those who have bullied you and make them treat you respectfully.” He said.……Later, she asked him with her hands on the belly,“Darling, there is a question.
