Has White Atsushi Transmigrated Today?

[I haven't written in ages, and I lost my drafts, so I'm abandoning this story. Sorry. (Bows)] After the war with the Guild ended, the president ordered Nakajima Atsushi to take a week off. The vacation felt so long that when he finally returned to the detective agency, he was so eager that he started hallucinating. Was that really Akutagawa in the agency?! He closed the door, then opened it again. When he met his teacher's playful smile, Nakajima Atsushi breathed a sigh of relief. But... The hallucinations became more and more frequent, and lasted longer each time. Only belatedly did Nakajima Atsushi realize that those scenes, which made absolutely no sense, weren't hallucinations at all! After standing there gaping at another version of himself, Nakajima Atsushi saw Mr. Dazai in a black suit and red scarf, and felt his worldview teetering on the brink of collapse. This world was probably doomed. And this was only the beginning of something insignificant. The extraordinary invaded everyday life, becoming part of it. After fighting with Akutagawa, he somehow saw a version of "himself" in a black suit shopping with Kyouka. Oh, in this world, I'm with the Mafia again. After being invited to the Mafia for tea, he was then "entrusted with great expectations" by that world's Mr. Dazai. He and Akutagawa fell from a hundred meters in the air and landed in another world... A world where, supposedly, he and Akutagawa were locked together in an intensive math training camp. Unwilling to take the place of a top student, Nakajima Atsushi tearfully buckled down to study and began his new routine of slacking off through high school (X). The road ahead is still long. Who knows when he'll make it home? Pairing undecided. Maybe it'll be decided by the market in the end. P.S. If there's a parallel world you'd like to see, leave a comment (important).
