The Greatest Love (최고의 사랑; RR: Choego-ui Sarang; also known as Best Love) is a 2011 South Korean romantic comedy television series about true love in the fake world of entertainment. Starring Cha Seung-won, Gong Hyo-jin, Yoon Kye-sangand Yoo In-na, it aired on Munhwa Broadcasting Corporation (MBC) from May 4 to June 23, 2011 on Wednesdays and Thursdays at 21:55 for 16 episodes.
Gu Ae-jung (Gong Hyo-jin) was the most popular member of girl group Kukbo Sonyeo, literally meaning "National Treasure Girls," some 10 years ago, but fell from grace after becoming embroiled in scandals. She makes appearances on television programs to eke out a living for her troublemaker father and brother. On the other hand Dokko Jin (Cha Seung-won) is the most beloved star in the nation, topping all kinds of popularity polls and appearing in many commercials, but has several character flaws. Ae-jung discovers a secret about Jin by chance and reveals it on a talk show, incurring his fury. However, their ill-fated relationship unfolds in an unexpected way as Jin falls for Ae-jung and tries to win her heart.
Another star Kang Se-ri (Yoo In-na), also used to be in Kukbo Sonyeo with Ae-jung. But whereas Ae-jung was more famous in her heyday and Se-ri was a nobody, now every girl wants to be just like Kang Se-ri. She dated Dokko Jin for a short time, but despite their breakup, they keep up the pretense that they’re still dating to avoid negative publicity. Se-ri is also the host of popular TV dating show Couple Making Season 3.
Yoon Pil-joo (Yoon Kye-sang) is a well-mannered, thoughtful and caring doctor of Oriental medicine. He has no interest in celebrities and their outrageous lives. Under pressure from his mother, he agrees to appear on a TV dating show, but after finding out that Ae-jung will also be appearing on the same show, he becomes very eager to meet her. Fictional dating show Couple Making Season 3 is based on MBC’s real variety program We Got Married, where they throw celebrities into fake relationships for the cameras. The concept is a competition-based mat-seon program, essentially setting up people on blind dates for the purposes of finding a marriage partner. The major difference is that in Couple Making, celebrity ladies compete over a non-celebrity eligible bachelor who gives them roses to prevent their elimination (a la The Bachelor), which is how Yoon Pil-joo ends up as a contestant on the show.
The mix of the main characters’ mismatched personalities with the necessity to maintain (or recoup in Ae-jung’s case) public sentiment makes for great hijinks and drama, not to mention an interesting meta social commentary on the entertainment industry and the star-making and -breaking power of image.
