In a Modern Matriarchal World: Brother, I'm Sorry

Xie Yanyu used up the greatest stroke of luck in his life when he met Ruan Qing and watched her grow up. Back then, Ruan Qing was adorable. She would always follow him around, sweetly calling him "big brother," and even declared that when she grew up, he was only allowed to marry her. But after she grew up, he was the only one who took that joke seriously. Ruan Qing had money, beauty, and talent. One strikingly handsome man after another came after her, and little by little, the two of them grew further apart. It wasn't until some time later that Ruan Qing suddenly realized that her big brother had always been the one hidden in her heart. What will happen to them next...?
