How can you make two people hate each other so much that even after their memories are erased and their lives restarted, they recognize each other at first sight, recover their memories, and draw their swords against each other?
An original novel where the process ends in tragedy, but the conclusion is happy,
a bunch of brainless tools who exist only to serve the plot,
side characters with all kinds of problems,
a pair of protagonists who keep hurting each other until they both go mad.
And finally, a little System, a hapless scapegoat that can restart the plotline and take out loans to fund cheat abilities.
Put all that together, and congratulations: this little world will never follow its original plot again!
From then on, the plot falls into chaos, the little world grows unstable, the story goes off the rails, character auras malfunction, the mission System breaks down, and everything else is just around the corner!
