Luna was arranged to marry the CEO of Craft Corp as soon as she returned from abroad after earning her Master’s degree. Coincidentally, her best friend Emily told her that she had used Luna’s photo to set up a date with a man named Chris online and suggested that Luna marry him to avoid the arranged marriage. To prevent her true, playful nature from scaring her husband away, Luna pretended to be graceful and gentle.
Little did she know, this marriage was part of Chris's plan. He had secretly harbored a crush on her ever since she saved him when he passed out in an alley abroad after being injured. When Chris discovered that their parents had arranged a marriage between them, he was ecstatic. However, Luna strongly rejected the idea. With his cousin Emily's help, Chris managed to marry Luna and started to act as her ideal type.
As they spent time together, both tried to maintain their façades while testing one another. Gradually, as their pretenses began to fall away, they found themselves falling for each other's true selves.
