It was korean drama called "The Greatest love". I wrote something before about this drama in my post about Cha Seung Won.
The story:
Ae Jung (Gong Hyo Jin )was once the most popular member of girl band The National Treasure Girls. However 10 years ago the band broke up and she received most of the blame. Despite her warm personality her career has suffered ever since and she now spends her time fighting for air time on variety shows. Dokko Jin( Cha Seung Won) is a top movie star at the height of his career. The two meet and become involved in each other's careers. Yoon Pil Joo (Yoon Kye Sang) is a doctor of oriental medicine who has no interest in the entertainment industry but agrees to make a dating show. Dokko Jin helps get Ae Jung a role on a new reality show called Couple Making. Pil Joo is the bachelor being set up on Couple Making. Both men fall for Ae Jung both off and on the screen.
Drama is one of my favourite drama. It's romance and comedy. The cast is awesome and play very good. From the beggining till the end drama is very nice to watch. For sure I will watch this drama for second time. I've already written about Cha Seung Won that he is very handsome and sexy actor. Also main actress Gong Hyo Jin is very good - I remember her from "Hello my teacher" - she played with Gong Yoo there.In every drama she is great so I really recommend this drama for everyone.
