I...AM...MOB CHARACTER!!!Sigh~My name is Samael, I was an office sla- I mean a worker who worked 9 to 5. It was a daily routine of monotony until one fateful day when I went home only to find my best friend with my girlfriend. Betrayal was the first thing I felt, followed by rage.And after taking ‘care’ of them, My surroundings changed…Looking at my reflection in a mirror, I noticed my appearance had changed. Gone was the face of the disgruntled office worker; instead, “SAMAEL ASHWOOD!!!” a character from a novel I used to read. But this wasn't just any character; I had become him—the sacrificial best friend of the protagonist who was betrayed and died in just the first two chapters.PROTAGONIST DIED!?[Heavenly Destiny System Initializing...][...]

- Description from Novelupdates

The MMORPG ’EVR’ was released unexpectedly one day, along with its advanced equipment that allowed players to fully immerse themselves in the game, even though prior VR technology wasn’t nearly as realistic. To prevent people from replacing their real lives with the game, the servers were shut down during the day and on weekends. I was the best at the game, but since I had no friends or family, I could only watch and bet on sports while waiting for the servers to reopen—until the day I died and regressed to a week before the game was released. I know everything that will happen in the game. I know the game is not just realistic; it’s real. And for some reason, I don’t need to log out!
