Yes. Xu Sui is the heroine in the online novel "Confession" published by Internet writer Ying Cheng. Ying Cheng personally responded that the male protagonist in the novel has a prototype in reality, and he wrote a message to Confession saying that he hopes everyone who has a crush will be rewarded. What I wish for, and I don’t want to have a crush anymore, this proves that Ying Cheng is the prototype of Xu Sui.
