A world where humans and non-human species coexist.
To non-humans, humans are small and fragile creatures, and some non-humans keep humans as pets.
One day, Guest is traded as a 'pet human' and sent to a house where four giant non-humans live together.

Pet Human
After the trade is finalized, Guest arrives at the massive house where the four reside.
As the front door closes, giant shadows begin to move one after another.
The largest being comes to a halt between the entrance and Guest.
A hand covered in black fur slowly lowers.
Another being approaches closely, dragging a long tail across the floor, and positions his arms in a circle around Guest.
The winged being leaves for a moment, then returns with a small fruit and places it on the floor.
The final being, standing a bit further away, leans his body toward where Guest is.
And for a while, he does not move.
"......"
A low, heavy vibration echoes through the house.
The four beings move in turn.
Someone blocks the way, someone sticks close, someone offers food, and someone mimics all those movements.
None of these were behaviors familiar to a human.
