"You're the Best Lee Soon Shin" IU's family begins to suspect Jo Jung Suk of being IU's romantic interest.

April 7, the 10th episode of the KBS weekend drama "You're the Best Lee Soon Shin" featured Shin Joon Ho (Jo Jung Suk) being treated like Lee Soon Shin's (IU) boyfriend by her family members.

Shin Joon Ho attempts to convince her family members to support her in trying to become a celebrity by revealing the truth about her contract with his entertainment company. However, when he arrives at her home, Lee Soon Shin tries to hide his identity.

Lee Yoo Shin (Yoo In Na) asks, "Did you come all the way over here to get permission to date?" and Lee Soon Shin replies, "That's it. But right now, we're nothing."

Lee Soon Shin's grandmother Shim Mak Rae (Kim Yong Rim) responds, "Do you know how long it's been since your father passed away? And you bring your boyfriend here? And how do you show up to a house full of only women without even calling first" and continues to scold Lee Soon Shin and Shin Joon Ho.

Shin Joon Ho gets dragged out of the house by Lee Soon Shin. Lee Soon Shin's mother Kim Jung Ae (Go Doo Shim) follows after then and overhears that Shin Joon Ho is the president of an entertainment company.
