IU revealed that the reason she took up her role in You′re the Best Lee Soon Shin was Yoo In Na.

The leads of You′re the Best Lee Soon Shin, IU, Jo Jeong Seok, Yoo In Na, Son Tae Young and Jung Woo, appeared on the May 2 broadcast of KBS2′s Happy Together to talk about their drama.

When asked whether she felt any pressure about her first lead acting role, IU said, "I did feel a lot of pressure. The previous dramas, Unexpected You and My Daughter Seo Young, were so successful that I was worried whether I would be able to fill this big space."

In the end, Yoo In Na gave her the advice that pushed her forward.

"I asked for help from Yoo In Na, and she strongly recommended that I go for it," she said.

Yoo In Na later joined IU in the same drama.

IU said, "I saw the script and there was a sister role that seemed would fit Yoo In Na well. At the time, Yoo In Na had been talking about joining a different piece, but in the end she came to join us after she was offered the sister role."

Yoo In Na praised IU, saying, "IU is very good at acting. I recognized her talent, and told her she had to be in this piece."
