"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 raised without knowing love has dedicated his life solely to swearing loyalty to his master.

Etiquette. Guard arts. Knowledge. Refinement.

He learned everything necessary to serve a master.

But—

Love was the only thing he was never taught.

Five Commandments of the Butler

At the butler academy, there are five commandments that every butler must observe.

I. Prioritize the master above all.

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.

Shion, having received his diploma, 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 of butlers."

With those words in his heart, Shion came 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 mark 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 fell in love with such a Shion.

So you decided.

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

The Head Butler who knows not love.

Can you make him, who sees only his master, turn his gaze toward you?
