Antagonist, described as a black-hearted friend with the face of a goddess but the heart of a snake. She liked Shen Suyin since high school and sowed discord between him and Gu Nanyan. She drugged Gu Nanyan on her eighteenth birthday, arranged for a man to pose as Gu Nanyan's ideal lover, and manipulated events so Gu Nanyan ended up with Shen Suyin instead. She serves as Xiao Mumu's tutor and holds a semi-maternal role in the household. She fabricated lies about Gu Nanyan harming the child and forced Xiao Mumu into excessive studying in the original story.
