Earlier this week,�4minute's�HyunA and Jiyoon hyped up fans with the releases of individual teasers for the group's comeback -- today was Jihyun's turn as the leader turned up the sexy factor with a steamy video teaser of her own. Having received recognition for possessing�"bagel girl" charm with her baby face and glamorous body, Jihyun proves in this teaser that she knows how to rock the mature "STEAL 20" concept as well while maintaining her sweet allure. As she spritzes perfume on herself, Jihyun muses,�"My image in the mirror, it's not the same everyday.�What I've shown of myself so far, it's not everything.�A secret that I only know, hidden deep within me, I will now show it." The teaser ends all too soon with the now-familiar question: "Mirror, mirror, who's the prettiest in the world?"
