Korea's national 'little sister' is back with an all-new music video that plays up her youthful charm. Like in the French film, 'Amelie', IU's music video for "You and I" brings out elements of fantasy and ties it together with a well-crafted story. Since her album,�'Last Fantasy', is meant to reflect that period in her life where she bids farewell to childhood and prepares to meet maturity, the MV (also starring actor Lee Hyun Woo) does a great job in expressing that theme. Check out her nine-minute music video below, give the rest of her album a listen, and stay tuned for IU's comeback performances later on this week! [gallery]
