Sanok's daughter. Assistant manager at HS Fashion.
"I am sick and tired of living with my mother arguing every day, so I dreamed of living a happier life with a cool and smart mother-in-law. Then, I realized I jumped out of the frying pan into the fire..."
When she remains silent, Jinae looks like a graceful woman. However, when it is a matter of her honor and pride, she even goes through fire and water to fix it.
She has a "love and hate" relationship with her mother and eventually decides to stand on her own, especially being independent from her mother.
One day, Kang Hunjae shows up in front of Jinae, who is looking for a way out and she falls in love with him.
Yet, after getting married to him, Jinae begins to understand Sanok struggling with her mother-in-law.
