Even though Jaehee is a fairly serious and independent business woman, she is very caring. Jaehee 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.
