Three years ago, Si Nan went away to a foreign country to save others. On the first day after returning to China, Si Nan got drunk and lost his virginity, vowing to find that woman. All this was planned by Gu Weiyan, the president of the Gu family, who fell in love with him at first sight three years ago. In order to escape family marriage, Si Nan actually tried to match her up with his eldest brother, but through frequent contact, he gradually fell into the love network she had already woven.
