She didn't want a typical love line in the drama. She thought that there were plenty of other elements that could bring entertainment to the drama to attract the viewers. In that sense, tvN Friday/Saturday drama "Incomplete Life" was unique and now it's proven that actress Kang So Rah's thoughts were correct.

Kang So Rah was a fan of the webtoon, the original version of "Incomplete Life" and had a very different determination from the very moment she was cast. As much as there were a lot of expectations based on the webtoon that was very much of a burden, she had concerns about the role of Ahn Young Yi.

There were also concerns of those around her as to whether she could fully play the role. Nonetheless, Kang So Rah was determined and approached this role. She even went to Dae Woo International and worked for a week to learn the way of life.

She also paid attention to the details of a person at a workplace. From basic things such as making copies to making coffee, she increased her computer skills as well so that people could relate to her as if she was really working for the company.
