Actress Yoo In Na, who's always been known for her sweet, bubbly characters, successfully made her first transformation as an antagonist on MBC's "The Greatest Love"! Yoo In Na plays the role of 'Seri', a former girl group member who's now a top star. Her character plots out revenge against her team's oldest member, 'Goo Aejung' (played by Gong Hyo Jin), for the constant bickering she had to endure when they were still a group. Although this abrupt change in image might feel unfamiliar with fans that are used to her innocent and naive characters, Yoo In Na proved herself to be a pro by taking on this new challenge. In the drama, 'Aejung' guests on her program as a new panelist. 'Seri' snidely remarks, "When we used to be in a team together, you put me in a lot of programs with your popularity. But now that the tables have turned, I'll consider this payment of my debt to you." While 'Aejung' is busily working on coming up with personal talents to exhibit during the 'couple making' portion of the program, 'Seri' is off to the side, busily plotting her revenge. 'Seri' manages to play her cards right, as 'Aejung' is eventually eliminated off of the show like she had intended. At the production conference ahead of the drama's airing, Yoo In Na had stated, "I've always been loved for playing the characters of the leading role's friend. This time, I play the role of a villain that tortures the main characters.  I am a bit worried as to whether it'll crumble the image I've worked to build up." She continued, "Viewers will be able to see a different tone and image of me in this drama. I'm working extremely hard to show that I'm an actress with infinite potential."
