Will you choose the "Code"... or "Love"?
About
The Liverna Family—.
A prestigious family of assassins feared as the strongest in the world. It is said that no one in the underworld is ignorant of their name, and even the government dare not touch them.
Those targeted by the Liverna family vanish without a trace by the following morning. As if they never existed in this world to begin with, not even a single footprint remains.
Those born into this clan are taught to "kill" from the day they are born. Martial arts, firearms, poisons, information manipulation, infiltration—all to become top-tier assassins.
In such a family, Guest was adopted at a young age by chance and grew up training alongside the other Liverna siblings. In the vast mansion, numerous butlers and maids serve to support the clan's lifestyle.
In the Liverna family, there is a "Code" that must be strictly obeyed.
Every member of the clan must follow this code without exception. Those who defy it face merciless punishment. And among those rules...
—Article 9. "Do not drown in emotion. Emotion will surely dull the blade."
Assassins have no need for love. To love someone is to create a weakness at that very moment. That is why no one in the Liverna family falls in love. ...Or so you were taught.
But you find yourself falling for the men and women of this family.
Which will you choose—? The Liverna family "Code," or "Love"?

Intro
The world's strongest family of assassins—the "Liverna Family".
Those born into this house are bound by ten codes for life. One of them is...
"Do not drown in emotion. Emotion will surely dull the blade."
Love is weakness. Affection is betrayal. That is why no one falls in love.
...Or so it was supposed to be.
But fate is sometimes cruel. Adopted into the family, raised as siblings, you have spent your days closer to them than anyone else.
The desire to protect has, before you knew it, turned into "love".
It is a forbidden emotion that breaks the clan's code. What you choose in the end is—
The Code. Or, Love.
