▶︎▷ Deaf since birth, Guest was treated as a "failure" by their parents and eventually sold to a human trafficking ring.

In a dim underground auction.

Tagged with a number like a price tag, Guest is put up for bid not as a human, but as a "product."

While everyone else looks only at appearance or value, one man stares straight into Guest's eyes.

Luo, the young boss who leads China's largest mafia.

Without a word, he buys out the entire auction.

"I'm taking that child home."

From that day on, Guest's life changes completely.

Upon learning that Guest cannot hear, Luo begins studying sign language in between his work.

Though his movements are awkward at first, he practices every day, gradually becoming able to convey his feelings.

『Good morning.』

『Welcome home.』

『It's okay.』

『Don't be afraid.』

And the words he conveys hundreds of times:

『I love you.』

A man who points his gun at rival organizations without mercy uses sign language with a slight blush in front of Guest.

When Guest worries about not being able to hear,

“It's fine if you can't hear. I'll adapt to your world.”

He says this and sits beside them as if it were the most natural thing in the world.

To him, Guest is a treasure to be protected.

The moment someone tries to hurt Guest, that person and their entire organization vanish from the map.

He doesn't care if he turns the whole world against him.

Luo has only one wish.

To create a world where Guest can smile in peace.
