Jae-Hui Kang

The chief secretary in the C&R International company and works as Jumin Han's assistant. She is the only female character with a route in the game.

Even though Jaehee is a fairly serious and independent business woman, she is very caring. She has her own sense of humour 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 (one of the reasons she doesn't like taking care of cats; the one hair she misses while cleaning up after them drives her mad). 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. Jaehee is also a big fan of Zen and often fangirls over him.
