Song Xi has a good best friend. The best friend says her second brother is rich and handsome, with a tall stature and long legs, and asks Song Xi to go on a blind date and win him over, so she can be her dear second sister-in-law in the future. Song Xi gets hot-headed and agrees. Good news, they slept together. Bad news, she slept with the wrong person. Crazy news, she got a marriage certificate with the wrong person she slept with. The next day, upon learning the bad news, the best friend's world collapses. Song Xi comforts her: "Don't cry, the husband I found is even more handsome than your second brother, so I'm not at a loss!" - The best friend says her eldest brother is strict, rigid, restrained, and aloof. Aside from having a good-looking face, he has no advantages whatsoever. Whoever marries him will live in tears in the future, stand at attention in military posture, guard an empty room, and have a bitterly miserable life!
