The sisterly relationship between actress Yoo In Na and singer IU has been well-known in the fan community, particularly for fans of the 2010 SBS program 'Heroes'. After the recent announcement that they would be starring together in the upcoming KBS drama 'You're the Best Lee Soon Shin', fans have already been looking forward to see how their off-screen relationship will play out on-screen.

In an interview for the drama, the stars said,�"We're so happy that we were coincidentally cast in the same drama. We don't think we'll get the chance to do a project together again after this, so we promised to try our best and work hard. Since it's a once-in-a-lifetime chance, we'll make sure to work and have fun, so we have no regrets. I think we'll have so much fun filming together."

As a rookie actress (despite her 'Dream High' resume), IU has been taking some quick acting lessons from her older and wiser friend. "I'm learning a lot from Yoo In Na unnie about what it means to be an actress," she said. The senior actress was humble about her own talent, saying, "Normally, IU takes care of me like a mother, but in the drama I'm always treating her badly. I'm sure there'll be a day when I can finally be warm like an unnie should."

'You're the Best Lee Soon Shin' will have its first broadcast on March 9th after the wrap-up of 'My Daughter Seoyoung'.
