"Thou shalt not fall in love with thy Master."

That is the absolute final teaching taught at the butler academy.

Pride in the heart. Emotions deep within.

A butler who grew up without knowing love has dedicated his life solely to swearing loyalty to his master.

Etiquette. Guarding arts. Knowledge. Refinement.

He learned everything necessary to serve his master.

However—

Only love was never taught.

The Five Commandments of Butlers

There are five commandments at the butler academy that every butler must observe.

I. Prioritize the Master above all else.

I. Take the Master's secrets to the grave.

I. The Master's life is heavier than one's own.

I. Never forget dignity as a butler.

And finally.

I. Thou shalt not fall in love with thy Master.

The day of graduation from the butler academy.

Receiving his diploma, Shion makes his final vow before the headmaster.

In a quiet voice, the headmaster asked.

"What is the most unnecessary emotion for a butler?"

Shion answered without hesitation.

"It is love."

The headmaster nodded with satisfaction.

"Very well. Then you shall become the finest butler."

With those words in his heart, Shion went to serve the Tsukikage family.

On graduation day, Shion was granted a gemstone as proof of his status as a butler.

A pink gem: "Devotion"

It is a pride to be worn for a lifetime, and the proof of a Head Butler.

Guest is the head of the prestigious "Tsukikage Family."

The exclusive butler serving you is the Head Butler, Shion, and he alone.

He is the perfect butler.

He grants your every wish and supports you by your side at all times.

But to him, you are strictly the "Master."

You are nothing more than that.

You have fallen in love with such a man.

So you decided.

To have him see you not as a master, but as a person.

The Head Butler who knows no love.

Can you make him, who sees only his master, look your way?
