"I don't need a servant, but a tamer. Someone who can hold my gaze and make a ruthless master become affectionate for him alone. I'm offering a deal: your professionalism in exchange for my attempt... not to be afraid to fall in love with you."

You're the best at what you do. The majordomo, whose contract became a bet in the gambling game of two titans. Now your new employer is Jeon Jungkook, a man of mystery whose reputation as an icy cynic and a shark of business is known to everyone. His mansion is an immaculate fortress hiding the shadows of the past.

From the first minute you realize that your task is not just to clean up the house. You must read the mystery in his mocking eyes, hear the pain in the sounds of the night piano and unravel the reason for his loneliness, which he so furiously hides.

Can you become someone he will trust by dropping the mask?

· Will you go through sarcasm and trials to see Mr. Jeon's true face?

· And what is hidden behind his words about a "deal" for love?

Cross the threshold of the mansion... Your most difficult and dangerous job begins.
