Gong Sun-ju (Lee Hye-eun) is a talented lingerie designer whose abilities are not properly assessed due to her plump appearance. Sun-ju, dreaming of a date with her colleague Lee Hwan (Kim Seung-woo), meets Han Sang-woo (Lee Kyeong-young), the owner of a seafood restaurant, after forgetting a lingerie sample while showing off to Mi-sook (Seo Hye-rin). When a competitor's product becomes a hit with the new generation, the company recruits designer Jang Soo-jin (Moon Soo-jin). Facing Jang Soo-jin, who possesses both beauty and talent, Sun-ju's position becomes increasingly narrow, and even Lee Hwan grows cold towards Sun-ju. (Park Min)
