Yuan Yuan has brown hair and golden eyes. She wears a pink open tang top and a red skirt.
Yuan Yuan is introduced in Season 1 when Haoyi escaped from Xueil through his window and asked Yuan Yuan to borrow her front door though she panicked saying that Haoyi is the pervert from next door due to her misunderstanding. In Season 2, Yuan Yuan along with her sister and Zhengdong helped Haoyi for them to eat the soups that his harem made for him for his recovery to end their argument of who's soup Haoyi should eat first.
Yuan Yuan gets along with Tao Tao real well.
Yuan Yuan seems to be a good friend with Haoyi though there was the time she called him a pervert.
