Waking up in another world moments after he fell asleep in the middle of work wasn't something he expected to happen in his life. But it did, and now he was in Remnant… born as a young Jaune Arc nonetheless. However, things are not as they seem… as he realized, this may be a different Remnant from what he knew, in fact, it was one he was far too familiar with. It was a Remnant which he wrote himself.
Self-Insert (but not really) as Jaune Arc, Crossover Elements with a lot of Korean Webnovels (mainly I Came Back and Conquered it All).
