Kim Seon-ah put her performance to the extreme.
Kim Seon-ah portrayed the pros and cons of a single character without so much excellence.
Park Bok-ja had a job interview as Ahn Tae-dong's (Kim Yong-gun) caregiver and had dreams of upgrading her status. When she first met his second daughter-in-law Woo Ah-jin (Kim Hee-sun), she was intimidated and indulged in materials as to not make mistakes.
Soon, she was eliminating anything in her way to fulfill her passion and desires and completely had the trust of Tae-dong who would let her give out the shots. She ended up being the biggest shareholder in Tae-dong's company which he had worked on his whole life. She was now the chairwoman of it. She soon adopted the tone and gesture of ordering people around like she was a natural at it.
