Not much is known about Sarah's true personality other than her greed when it comes to money. She seems to be very loyal to her sister, Glam Choi, and is willing to go through tedious tasks to get what she wants. Sarah doesn't seem to be afraid of flaunting her looks and position as she calls herself Jumin's fiancée, despite his arguments to the contrary.

She portrays herself as an upbeat woman, very cheerful and caring. When talking to those other than her sister, she displays a fake persona. She seemingly pretends to act hurt and defeated when her advances on Jumin don't work, though sometimes making joking remarks at how cold he is towards her. She is the primary antagonist of Jumin's route.

Voice Range: Medium to medium-high pitched. A little whiny and dramatic.
