"You're the Best Lee Soon Shin" When Jo Jung Suk finds out about IU's audition, he becomes furious.

April 28, the 16th episode of the KBS weekend drama "You're the Best Lee Soon Shin" featured Shin Joon Ho (Jo Jung Suk) finding out that Lee Soon Shin (IU) was unable participate in the audition for the drama all because of Song Mi Ryung (Lee Mi Sook).

Shin Joon Ho goes to see Song Mi Ryung and says, "What happened with Lee Soon Shin's audition?"

Song Mi Ryung replies, "I pushed her because I thought she had potential but I found out she is nothing. I think it will be an insult to me if I worked on a same project with her. She just is not it."

Song Mi Ryung had changed her mind about Lee Soon Shin as soon as she found out about her family history. Lee Soon Shin is the youngest daughter of a man who Song Mi Ryung had an affair with. On top of that, Lee Soon Shin's father had died from trying to save Song Mi Ryung's life. Even though Song Mi Ryung is currently unaware of the fact that Lee Soon Shin is her biological daughter, she decides to abandon her daughter once again.
