The type of series you forget 5 seconds after you read it. It's so safe and generic it's basically interchangeable with a hundred other series. MC plays a VR game and levels up, that's it. The whole thing is very casual. No one is trapped in the game. People can leave and come back any time. MC never struggling with anything. He goes from casual gamer to millionaire esport champion because he helped a random NPC... It's ridiculous but also seems to be the most popular genre right now. The only positive thing I can say is that because it's so simple you can flythrough chapters and not miss a thing.
