Der Absolutwert von Liebe

A quiet student by day, a romance novelist by night, Eui-ju is inspired when four gorgeous teachers appear: icy Woo-su, lively Da-ju, gruff Gi-jeon, and gentle Dong-ju. She writes them into her new novel, which blows up overnight! But her secret is discovered by Woo-su, her worst enemy since day one. She accepts his deal to protect her secret, but can she finish this novel unscathed?
