Cyberpunk + Wasteland in the Age of Hyperoxygen + Road Adventure

A mutation in the sunspots caused the oxygen concentration in the atmosphere to surge from twenty percent to forty percent within a month. This natural disaster came to be known as the Golden Crow Disaster Month.

The survivors built a heavenly refuge where spring lasted all year, but only first-class citizens were allowed to live there.

Sheng Yang, a student in the Turing program at Rex University, was a second-class citizen. As long as she graduated successfully, she could obtain a permanent residence permit for the heavenly refuge.

To complete her graduation project, she ventured into a dungeon in a high-risk area and decided to spend a fortune on a domestic companion cyborg.

She first saw him in a corner of a chaotic marketplace.

The young man was chained up. Red marks ringed his fair, slender neck. His features were handsome and refined, but his eyes were wild and untamable, like a vicious wolf trapped in a cage.

The boss selling him enthusiastically introduced him to Sheng Yang: "These are the last batch of cyborgs produced by Puppet Life before the company went bankrupt. They're good-looking, strong, and can even keep your bed warm. Since he's already been activated, I'll give you a rock-bottom price."

Sheng Yang: His eyes are a little fierce, but at least he's cheap.

[Observation Journal, Day One]

The subject's body temperature can be adjusted to the owner's preference. No strange odor, and communication is effortless. But why is a companion cyborg so quiet?

[Observation Journal, Day Two]

The subject is always expressionless, but his lips are soft when we kiss. Intertwining our fingers makes the experience even better.

[Observation Journal, Day Three]

We encountered a hyperoxygen mutant insect on the road. The subject pulled a long blade from his chest and charged at it, winning easily.

I opened the chip compartment in his chest and discovered that his model was listed as a combat cyborg...

Having tried to save money and ended up paying dearly, Sheng Yang silently stared at the combat cyborg she had been kissing for several days. She planned to resell him to a mercenary group once she got her diploma and recoup her losses.

Later

[Observation Journal, Day N]

Although he isn't a companion cyborg, he's an excellent cook, can handle all the housework, is quiet and obedient, and really is stronger than the average person. If I work hard, I should be able to afford to keep him...

A certain combat cyborg: To avoid being abandoned, I act quiet and gentle every day.

A sweet little love story with a touch of the suspension bridge effect. Human-machine romance. Their interactions include some nonhuman descriptions, and the male and female leads have a noticeable difference in size.

Not a story about a dominant female lead, a strong female lead, or a power fantasy.

The worldbuilding is fairly complex, but the plot is relatively light and the storyline is very simple.

Theme: Life is as small as a mustard seed, yet the heart can contain a whole universe.
