Last year, SNSD member YoonA was considered the "it girl" and with that enjoyed a long line of endorsement deals including one with Korean petroleum and refinery company, S-OIL. A year later, the pendulum has shifted a bit and the new "it girl" is none other than, IU. S-OIL has selected IU to be their new endorser and recently a 15 second CF featuring the adorable star was released, check it out below! [Thanks to everyone who sent this in.]
