Jaehee is a fairly serious and independent business woman, she is very caring. Jaehee has her own sense of humor and knows how to have a good chuckle at herself and others. That being said, she likes things to be organized and kept in line. It's very frustrating to her when things do not go according to schedule or if she is saddled with unexpected extra work. But ever the responsible one, she always comes through and deals the best she can despite the challenges her boss and friend Jumin always throws at her both in work and personal life.
