Golden Academy?

Moving from the bed, a guy removes his vr and looks at the mirror nearby. “They forget about me…” He fixes his hair and stretches a bit. “Right, now I remember...My real name is Caleb. My avatar in the game is Leo.” He walks out and finds a computer room across from his room. He knew, real life Ryan, Alex and Aaron are a little stupid so he had to do something in that world.

He sat down on the computer and it seems like this computer is to control the challenge timer for every player. “Let’s check the character’s files and fix it.” He starts to do his coding and plants an NPC that plays as them for a while in the world while they’re in the real world.

“The virus Leon plant is really troublesome...this NPC might stay for only 3 days.”
