It's a typical day in the Miasma Forest, if you could even call it a day because the sun's rays never reached the forest. Since miasma came, the forest never had a quiet and peaceful time, aggressive beasts, blood rivers and wait what? A Bed?!
In the middle of the forest where beast are supposed to be in a neverending hunt for prey, a bed full of pillows with the most beautiful man sleeping on it appeared. The moment this bed appeared, everything in the 10 meter radius seemed to calm.
A black and leafless tree about to sprout out it's roots to whip a rabbit suddenly regained it's long lost brown trunk and roots and is seemingly growing new green leaves.
The red rabbit (probably stained by blood), with dark red eyes, seemingly just went through the best bath it had in it's life and gained a very fluffy white as snow fur and emerald green eyes.
The ten meter radius just went through a transformation within a minute, the miasma receded and the long lost green was once again seen in the Miasma Forest.
On the other hand, the pacified Green-Eyed White Rabbit who unknowingly survived a sure-death encounter ran around the perimeter, surprisingly knowing the bounds of the radius and not leaping beyond it, in fear of once again getting infected by miasma.
Enjoying it's new lease in life, the Rabbit bounced around not caring whatever it bumped into, it bumped into the tree and rolled around the weeds.
After having exhausted it's energy, the Rabbit finally noticed the white bed in the middle of the clearing, so it cautiously stalked the bed and silently leaped around till it got within touching distance of it.
It inspected the bed, but the moment it's body felt the fluffy comforter, the urge to play in it once again excited the Rabbit.
So it climbed the comforter and got on the bed. Seeing all the obstacles (pillows) on top, the Rabbit couldn't help but bounce around and play.
It jumped around between all the pillows with no care in the world. However, when it was about to jump around to the fifth pillow, a pale white hand grabbed and brought it to the beautiful man's chest and hugged it tight, putting a stop to all it's shenanigans.
"Bun Bun", the sleeping man then murmured while not letting go of the still energetic Rabbit.
Hearing what the man said, and knowing full well it cannot escape given how strong the human's grip was, the Rabbit resigned to it's fate.
Remembering what it's mother taught it before the miasma arrived, if a human gave you a name, it means that you are now their partner and they will make it strong.
So the Rabbit accepted the name, if it could play around all day in this fluffy playground and even get strong, why would it reject?
The sleeping beautiful man, Kane, unknowingly just arrived in another world, made a miasma free perimeter in the Miasma Forest and contracted a very hyperactive cute White Rabbit all the while sleeping.
Fun right? Getting thrusted to maybe one of the world's worst Beast Zones with just your bed and a cute harmless? Rabbit. Fun!
