Cold Bed on Route

Have you ever heard of "The Cold Equation", the seminal science fiction novel of the 50's by Tom Godwin?
A spaceship sails at the edge of its weight, carrying a cargo that could save many people. An unscheduled person stows away on the ship.
If the stowaway is not thrown out of the ship, the spacecraft will be overweight and unable to follow its original course, making it impossible to save lives at its destination.
However, if the stowaway is thrown out into space, he/she will of course die.
Still, considering the number of lives that can be saved, the only way to save as many lives as possible is to kill the stowaways and abandon them...

This is the basic structure of "The Cold Equation" and the genre of "equation stories" derived from it. "Cold Bed on Route is inspired by "The Cold Equation" and its basic flow is in line with the "equation stories".
The story takes place on a spaceship drifting in the cold space - the ship, which looks more like a plant seed than a spaceship, is called Final Emergency Boat (FEB), designed to be super small and super light.

Because this work is an "equation-like" story, there is a stowaway.
The heroine of "The Cold Equation" is a fragile girl who stows away to meet her brother.
The girl in "Cold Bed on Route" is different. She is an artificial human called Doggy. Doggy has animal ears to distinguish her from humans. Her body is equipped with flesh, bones, and blood just like humans, but she is far stronger and more intelligent than humans.

Work with her to find and dump unwanted items. Then, let's make up for the excess weight caused by having her on board - a weight that is a little, well, a lot heavier than it looks. And let's prove that the universe is not yet completely cold and frigid. Now, pilot, it's your turn.
