MTL - The Troubleshooting Diary at Hogwarts - Chapter 17 Sunny on February 14 (Part 1)

Thousands of years ago, the First Expungement came. The world changed, and humanity was nearly wiped out. Thankfully, with the paracausal power of Angelicas, humans was able to push back the Ghost tide and rebuild their civilization.

Now, however, it was time for the Second.

Finn Thresher was just a normal university student at first. He, like the rest of the public world, had no idea what was coming for them — but sometimes, just because you don’t know, doesn’t mean you can’t be harmed.

His family… his sight… his purpose. All lost to the paranormal.

It was time to abandon his beliefs. To throw away his morals.

After all… if these creatures weren’t human anyway, there was no point in showing them humanity.

In the first battle of this war, the Ghosts won, nearly driving the human race to extinction. In the second, the humans fought back with the power of Angelicas and managed to secure a victory.

Now, the third and final round was approaching — and this time, it’s personal.

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…

Kira was living the life that others could only dream about. He was gorgeous, rich and very popular - the kind of guy that drew students from all over the place just so they could brag to others that they went to the same school as him. He was undoubtedly the number one heartthrob that every girl dreamed about.

A third-rate painter in the past life, and a chaebol in this life.

I thought it was a rebirth flow, but it turned out to be a system flow. I wanted to rely on myself, but you let me use a plug-in.
