The plots are all original and any similarities are purely coincidental.
I tried my best to imitate the original work but it turns out it is still not rigorous enough. I welcome corrections and point out bugs.
The timeline is in season one.
The plot jumps a bit too fast, I promise it's just a short story, abbreviated.
Finally, don't believe in the protagonist column. Because of a change of thought, the supporting character becomes the real protagonist.
