Shim Yi Young said that she would take after the kids and be a new person to Lee Sung Jae.
On the final episode of SBS Monday/Tuesday drama "The Suspicious Housewife" broadcast on November 26th, Woo Na Young (played by Shim Yi Young) is slapped by Park Bok Nyuh (played by Choi Ji Woo) and tells Eun Sang Chul (played by Lee Sung Jae) that she'll take care of the kids.
Woo Na Young started to yell in an upset way to Park Bok Nyuh who just showed up at her wedding shop and started to hit her.
However, Park Bok Nuh said, "Just be upset like this. Don't force yourself to laugh if you want to look after your kids. That promise to take after your nephews. This promise is not going against that promise, right?"
At this, Woo Na Young said to Eun Sang Chul, "I think I know whay Park Bok Nyuh was like this. I just wanted to act like an aunt and said things to Bok Nyuh."
She also promised, "I'm going to act like an adult now for the kids. I'll scold them when needed and applaud them when needed and really be like their mother.
