It's a one-shot, so really if you find it interesting there isn't much to lose.
I will now proceed with spoilers
This story tells the story of a girl who is repeating her life over and over again, trying to desperately fix her life so that she won't be bullied. But no matter how many times she is reborn, the same things happen. It is quite a fascinating short read, and I'm sure it's able to touch some people (though I am diagnosed with poker-face syndrome, and am unable to feel anything if it's not omori :') )
Like I said, if you found the title and cover interesting, there really isn't anything to lose because of how short it is, so why not give it a try?
