In the Vice President of ELN's secretarial office, Han Seo-won is impersonating her brother as a newly employed secretary.

Because of his new secretary, Vice President Lee Kang-joon can't sleep. Would his vivid dreams spiral the man out of control?

"Sir, I think it is better for you to stop and rest."

"Rest? Because of you, I can't sleep."

Her heart thumped at that answer; somehow she knew this was something different from their past relationship.

"I'm going crazy dreaming of you moaning under me every night."

"Wh-what?"

"So I advise you to run away before you get eaten by me."

Can Seo-won keep her secret to the end?!
