[Sweetness of a flash marriage + getting older + mutual favor + dual purity] Lin Xia has a die-hard bestie. Her best friend praised her brother-in-law for being gentle, well-off, and good-looking, and encouraged Lin Xia to go on a blind date and become her aunt. Lin Xia nodded in agreement on a whim. Good news: a flash marriage. Bad news: wrong person. Surprise: Registered marriage with the wrong person. The next day my best friend learned that it was a bolt from the blue. Lin Xia comforted: "Don't be sad, my husband is better than your brother-in-law, he won't lose money!" - Her best friend said that her eldest brother is strong, cold, strict, self-disciplined and taciturn. Apart from his handsome appearance, he has no other merits. After marriage, he may shed tears and stay alone in an empty house.
