In the finale, Song Yunhui revealed a birthmark to shock the Liang family, and Liang's father instantly cried silently, telling the big secret 30 years ago, which made Liang's mother extremely sad.
Since Song Yunhui was helped by Grandpa Liang, not only let his mother-in-law accept him, but also let his father-in-law help him work again and again, openly and secretly treating Song Yunhui as a ** person, causing Liang's father, who already had a lot of opinions on Song Yunhui's son-in-law, to sit still completely, and wanted to deliberately make Song Yunhui a whole time to test whether this Song Yunhui really wanted to be with his daughter, or coveted the benefits given by Grandpa Liang.
Therefore, in the following life, Liang's father deliberately refused when Song Yunhui needed help, citing that he was too busy with work to have time. In the end, Song Yunhui, who was sensitive, thought that Liang's father deliberately made things difficult for him, and proposed to Liang Sishen to break up. However, on the day that Liang's father saw that his goal was finally achieved, he accidentally saw the birthmark on Song Yunhui's body, and learned from the token that the other party carried that Song Yunhui was the child he and his wife discarded back then.
It turned out that Song Jishan, Liang's father, had a child with his wife Liang's mother, but at that time, the Liang family offended too many big people in business, causing the two to give away their son Song Shen in order to protect their children when they faced a crisis. Many years have passed, but unfortunately the person who adopted the son has disappeared, so Liang's father and Liang's mother adopted a girl in order to relieve their heartache and named her Liang Sishen.
