Actress Kim Seo Hyung is expected to show Jo Yoon Hee a powerful 'in-laws world'.

Kim Seo Hyung appeared on KBS 2TV weekend drama, 'Unexpected You' and appeared as Chun Jae Yong's oldest sister and showed her charisma.

After ending the love triangle, Bang Yi Sook and Chun Jae Yong started to officially start their romance. However, Kim Seo Young is opposing the 'Chun Bang Couple.'

Aside from being Chun Jae Young's oldest sister, Kim Seo Young shows the very well known 'in-laws world' that 'Unexpected You' gave light to.

As it was seen through Bang Mal Sook and Cha Se Kwang's relationship, the 'in-laws world' can change depending on who's viewpoint it is being seen from. It can also change, and it is being seen once again through Yi Sook's future 'in-laws world.' Kim Seo Hyung plans to show the epitome of the 'in-laws world.'
