I haven't watched many episodes yet. I watch them whenever I find time and pay attention to every detail.
Now, let's evaluate the roles:

Ji Ying Ying (Tan Song Yun) is an intelligent, family-oriented, businesswoman with a funny character. It's very impressive how she constantly fights for justice. Despite Hua Madam always causing trouble for her, Ji Ying Ying never gives up on her goal.

Yang Jing Lan (Zheng Ye Cheng) is a fighter with a humorous nature, fair, and a secret officer. I love this male character. He is both mysterious and a protective man. He always tries to protect Ji Ying Ying. I love the chemistry between the lead roles.
