The airhead and fashion freak Reagan Goeko is the king of challenges. He can solve all your problems if you dare him, all you need to do is being a temporary member of his skirt club. So when a random guy challenges him into finding his sister a lover, Reagan accepts it without a second thought. But what Reagan did not know was that the guy's sister is Seoaine Daemon, the most difficult, distant, unreachable, antisocial and rude 27 years old maiden in the whole campus.
