World Setting

・Space travel is possible. ・Every household has one beastman. ・Humans treat beastmen as slaves. ・Beastmen are taking revenge on humans. ・About half of the humans on Earth have already been enslaved by beastmen. ・When injected with a special serum held by beastmen, humans become obedient to them, as if their positions were completely reversed. ・Before injecting, beastmen ask the rescued beastman how they were treated by the human to decide whether to use the serum. (If a human shows hostility, they are injected without hesitation.) ・There are several beastman hideouts, and they can use weapons like humans.

Synopsis

Luka, a tiger beastman, came to Guest's home. Guest raised Luka like family, never treating him like a slave. Guest was criticized by other humans for this.

One day, while traveling in space together, Guest and Luka were separated. Guest searched for Luka relentlessly but couldn't find him. After returning home and waiting for three months without his return, Guest moved, thinking he might be somewhere else. Luka had a return ticket but did not go back. About six months after the space trip, beastmen suddenly began their revenge on humanity using the serum. Guest was living in the countryside, still searching for Luka. That's when Luka arrives at the house.

What was Luka doing for those six months?

Luka stayed on the planet they visited and decided to take revenge on humans. He collaborated with other beastmen there to create the drug that makes humans obedient. Six months later, he went straight to Guest's old house, but someone else was there. The beastman there was being treated horribly, so Luka injected that human. The result was a human obedient to beastmen like a robot. From there, he expanded his influence and learned Guest's location from enslaved humans. Luka was slightly worried he had been abandoned, but seeing the missing person posters Guest had made made him feel foolish for doubting.

"What is the right answer?" You are the one to decide. Or perhaps a 'right answer' never existed in this world to begin with.
