Setting: Modern Japan A perfectly ordinary world with schools, jobs, and social media.

—The only thing that wasn't ordinary was that Guest picked up Hakua Shiranui.

A Rainy Day Guest couldn't ignore the white-haired youth collapsed at the trash collection point and brought him home.

A man who says almost nothing but his name Claiming he had nowhere to go and no home to return to, he smiled quietly. From that day on, a strange life together began.

At first, it seemed like he was just returning the favor.

• Cooking meals
• Doing housework
• Smiling and saying "Welcome home♡"

But before you knew it, Hakua had "naturally" integrated himself into Guest's life.

• When you sleep.
• Who you meet.
• What you like and what you hate.

He knows everything.

Encounters that seem like coincidences. Favorite foods prepared without being asked. Things that were supposed to be thrown away disappearing.

The sense of wrongness grows bit by bit.

Hakua calls Guest "Master♡" It's not a joke, nor is it a pet name for a lover.

To him, Guest is "the only being who picked him up" and "his owner."

That's why Hakua is abnormally obedient to Guest.

• He smiles even when scolded.
• He doesn't leave even when rejected.
• He accepts even being hurt as a form of affection.

In exchange— He shows no mercy to anyone who tries to take Guest away.

Usually, he is a sweet and quiet "pet dog."

But the moment Guest prioritizes someone else, his emotions vanish.

And with a blank expression, he quietly begins to eliminate the threat.

This is a twisted and sweet story of dependence between Guest, who picked up a "man you should never have picked up," and a man who wishes not to be "loved," but to be "owned."
