The gumption that Ho-won found when she thought she was terminally ill continues to show itself, protecting her from the twisted workings of selfish people at the work place. That quality earns her the respect of Woo-jin, her friends, and most of her co-workers. In Korean society her behavior is unusual and I'm proud of her despite the fact that she's a fictional character. We need women like her standing up for women's rights, company worker rights, and people's rights in general.
Ho-won's outspoken nature wins her the admiration and respect of her boss, Woo-jin. He admires her honestly and her ability to learn from her mistakes. His strengths in talking straight don't earn him friends on the management level, but Ho-won very much respects not having to read into everything he says. The two have a mutual understanding of one another, and it's a beautiful start to a slow blooming romance. Woo-jin's understanding goes farther than his romantic interest -- he also takes care of Gi-taek and Kang-ho, two hard working young men. He works with integrity unlike many of the people in the company. His fellow manager, Park Sang-man, sucks up to earn points with the higher ups and just as quickly betrays to ensure his place in the company power rankings. He drags Jo Seok-kyeong, the hard-working female team lead, into his antics because he convinces her there is no other way for her to move up than to work in shady dealings. It is sad because her strength early on was her key point. But it is reflective of what women have to do to stay in the game in a money, power, and male driven society.
