The biological daughter of the Su family, raised in the countryside for eighteen years after being switched at birth. She is reborn (having lived a previous life) and carries residual jealousy and envy from her past life toward Su Yuan. She plays the role of a sweet, pitiful girl outwardly but is secretly hostile and scheming toward Su Yuan. She manipulates Zhang Lanjun into giving her the third son's room and seating next to her at dinner. She refers to Su Yuan as Yuan Yuan and pretends to be kind while harboring malice.
