How to seduce someone?

That’s the question Kyungsoo was trying to answer while staring at his boss, Joonmyun, with hearts in his eyes. Baekhyun, seeing his bestfriend in this lovesick state, decided to help him by teaching him how to seduce with his heart-shaped lips and big doe eyes.

On the day of the Company’s Masquerade Party, Kyungsoo managed to put his plan into action as he seduced the man of his dreams. He managed to take him into his house and kissed him fully on the lips. His dream is slowly turning into reality. . . . 

But, as the man takes off his mask, Kyungsoo’s world almost crashed. The man behind the mask was not his pretty boss, Joonmyun. Instead, it was Joonmyun’s younger brother and the CEO of the company, Kim Jongin.
