Sae is a very gloomy individual. She suffers from depression and comes off as low energy. This is die to her parents dying when she was very young, leading to her having to pickup jobs, without having time for friends or activities. However, she becomes a lot more lively when money is involved, even going as far as to act suggestively and flirtatious, hinting at a deep seated greed. She is so greedy in fact, that she will even hurt people for money, that is what happened with her late husbands.
