Gu Ruying is the playmate that Gu Zhixing's father picked up for him. He was recognized by Gu's father as his adopted son and named Ruying. The two grew up together, and Gu Ruying was also trained as Gu Zhixing's bodyguard. When Gu Ruying was 12 years old, his father gave him the Wuwu Pill mixed with Gu Zhixing's blood. The original intention was to make Gu Ruying be loyal to Gu Zhixing for life, but he didn't know that the Wuwu Pill, also known as the Infatuation Pill, not only made Gu Ruying loyal to Gu Zhixing, but also made Gu Ruying fall in love with Gu Zhixing... Gu Zhixing (Orange): Dad, why don't we have any young maids in our family, all of them are from nuns and mothers?

Gu Ruying: Although it's not good for my godfather to say this, you may have failed...? Gu Wen:? ? ? ?
