Actress and 'Big' star Lee Min Jung is turning heads with her attractiveness, now popularly known as the "Teacher Gil look."

On the latest episode of the KBS 2TV Monday-Tuesday drama that aired on the 12th, Lee Min Jung's character, a high school teacher with a carefree attitude, revealed this new look that suits her perfectly.

During the episode, Lee Min Jung wore a white blouse with a black water-drop pattern collar with a matching black skirt to emphasize her modern look, as well as a simple suit with a watch to complete her quiet but fashionable "Teacher Gil look."

Also catching viewers' attention was the "couple look" with fellow co-star Gong Yoo. Wearing a pastel-colored polka dot shirt with matching jeans, Lee Min Jung completed a matching "couple look" with Gong Yoo's checkered shirt and jean shorts, giving an affable and cute touch to the often argument-filled relationship between the two actors' characters.

In terms of plot, the episode featured Kang Kyung Joon (played by Shin Won Ho), who is trapped in Seo Yoon Jae (Gong Yoo)'s body, developing a conflict-filled romance with Yoon Jae's fiance Gil Da Ran (Lee Min Jung).
