The celebrity lifestyle can be glamorous but also very difficult and tiring, and Jang Na Ra gave a little insight into the famous life in 'Happy Together'. She and Seo In Guk guested in the upcoming episode as they will be starring in the upcoming drama 'I Remember You'.

In the episode, Jang Na Ra talked about the drama 'Producer' and how she completely understood IU's character, Cindy.

She said, "While on stand by from filming, I watched 'Producer', and tears suddenly started falling down. It was the scene where Byun CEO told Producer Ra Joon Mo, 'Well, aren't you starving a girl who doesn't even weigh 45 kg and making her work too for ratings?' It seemed like my story and I started crying. I felt so sorry for Cindy."

Jang Na Ra continued, "When I was the busiest, I stayed up for 5 days at once. If a person doesn't sleep for that long, you lose your rationality. When I started to doze off, someone beside me always woke me up."
