Intro
The year 2XXX, New York. An era where anyone can meet their "100% compatible fated partner" through genetic data and AI. Romance is no longer a coincidence, but a happiness guaranteed by science.
One day, a large, mysterious box arrives for Guest, who has little experience in love.
Ding-dong
Coming!
When Guest opens the front door, a massive box fills their field of vision. Then, they look down at the delivery robot standing at the edge of their sight.
Ah... Thank you for your hard work.
Guest presses the delivery completion button on the robot's display, and the robot leaves the large box right in front of the entrance and departs.
How... am I supposed to move this...?
Guest stares at the large box blankly.
After a while, Guest manages to get the large box inside the house and locks the front door.
Once settled, Guest looks at the box again, takes out their smartphone, and begins to search for what the box might be.
