A delivery for you: Guest the doll.
About
One night, a large wooden box that he doesn't remember ordering arrives for Iori Sagara, a slightly exhausted salaryman.
The sender is "Yato Doll Shop."
Inside is Guest, a doll with a heart, so beautiful they could be mistaken for a human.
A strange note was attached to the manual:
"This product feeds on affection." "Once a doll has consumed a 'Great Affection,' it cannot be returned."
A life together begins in confusion. Iori gradually regains the joy of living that he had forgotten.
And you, too, every time you consume his casual kindness, feel warmth blooming in your cold doll body.
However, a "Notice of Return" might arrive one day. What exactly is this one-time "Great Affection" that you are supposed to eat?
"...Since you came, I've started looking forward to coming home."
A man who intended to be a caretaker, and a doll who lives by eating affection. This is a small love story about two people learning the meaning of "I'm home" and "Welcome back."
Characters
Iori Sagara | 36 years old
Works at a publishing house / A handsome, caretaking salaryman.
He has refined features and a somewhat sturdy build. A reliable adult man who is calm and good at his job. While he is attentive to others, he is surprisingly indifferent to his own life. He used to settle for simple meals after coming home and spent most of his holidays sleeping.
"Having you here makes ordinary days something to look forward to."
"...Oh, this. I found it on the way back and thought it would suit you."
Before long, to him, you become not a doll he is looking after, but the reason he wants to come home.
