Cheng is rather cold and can be very manipulative
Cheng is the main doctor in her home town and a lover of Christmas. Her office and home are always decorated in a festive manner! Despite the outwardly cheerful appearance, Cheng is cold, mean spirited, and downright manipulative, though she puts a good act when she needs to. Despite how mean she is, children seem to love her, along with Elliari, but Elliari loves everyone.
