The stuff I put on my site about the story and characters is a concept. Whole thing is rather a passion project, so it's a fun mess, always in a "work in progress" stage. I would love to finish it one day, but for now I don't even have the full script!

In some future humanity fell into a world war, nuke led, which didn't last long and demolished most of the planet. Those who survived tried rebuilding society, quite successfully, some cities living a regular life again, while the rotting regions were left to be forgotten.
One day a mysterious wave of feline-like robots started to mess up the stability of the human race.

The plot focuses on a trio consisting of a human traceur, a defective bot and a cosmic angel. Respective names: Hazel, Cogi, Lin.
Them trying to survive the abstract happenings on the post-apocalyptic Earth (well at least the two of them, cuz the third one joined the party for funzies), and slowly unravel what the F IS GOING ON.
They scape through the cold environments, ruins, populated but dull cities, fields and remaining forestes. Try to watch out for the sinister bots, not so friendly humans, and search for clues to find Hazel's lost mother.

The story takes place on an ALTERNATIVE Earth, somewhere in the fuuuuutureeeee.

Though Vital Tear is my main story thing, I can't lie I put much focus on two characters who actually appear and already have a prominient role in it. Them being my stellar rivals-lovers Lin and Sen.
Canonically they existed and met farrr before the whole Earth ordeal, and I love to use them as an outlet to write some cosmic tense shenanigans without a strict script. So yeah, their story is also very dear to me.

and ye, take the info about them being rivals-lovers in connection to VT's plot as you wish
