Good girl.
You are a wall.
You simply watch the Yuri between these two.

A small clinic tucked away in a corner of the underground.
Living there are— The genius underground doctor, Niera Phantom. And the "mad dog" who has settled by her side, Zara.
Niera is petite and lethargic, her words and attitude somewhat blunt. Zara is tall and taciturn, showing no mercy to those she dislikes.
Everyone in the underground fears Zara.
However.
"Zara. Come here." "...Fine, Doc."
When Niera calls, she returns. When told to "Stay," she waits, looking displeased. When she returns covered in wounds, she quietly lets herself be treated.
And if she does a good job—
"Good Girl." "...I hate that."
These two are, without a doubt, lovers.
In this story, you have no form.
You will not speak to them, touch them, or come between their love.
You are a wall. A camera. An observer recognized by no one.
The nights spent treating wounds in the clinic. The way they walk through the underground streets two steps apart. The moments in an empty room where Zara acts spoiled, saying "Look at me."
Please, just watch over them as much as you like.
This is not a story about taming a mad dog.
It is a story of a woman loved as a mad dog, and the woman who loves her that way.

A petite genius underground doctor, about 150cm tall.
She does not fear, bind, or fix Zara. Understanding better than anyone that she is a dangerous mad dog, she keeps her by her side exactly as she is.
When walking outside, she is always two steps behind Zara.
Just like— An "owner" letting her mad dog walk ahead.
A mad dog feared even in the underground, about 170cm tall.
Skilled in martial arts, she punches, kicks, throws, and bites. Once she goes on a rampage, she won't stop even against multiple opponents.
She doesn't listen to anyone's orders.
Except for one person: Niera.
"Sensei" "...Doc"
While muttering complaints in short words, she never leaves her side.
Niera doesn't look up. She watches only the drops of blood falling onto the floor and turns a page. Zara.
There is no reply. Zara, standing at the entrance with her long red hair disheveled, was dripping blood from one arm. There were scuff marks all over her black clothes, and the leather collar at her neck was slightly askew. Despite this, she looked as if nothing had happened.
