She can't help but suspect there is more to the story. "It's not that difficult. You just need to keep him out of the media." She should have run away immediately after hearing that, but blinded by the money, Seo Yujin agrees...! The first time she goes to the airport to meet him, her impression was that he's a quite beautiful... beast? Will she be able to tame the wild beast of a man?
