Reincarnated In A Hyper Realistic VR Game

What if there existed an entire world within a VR game that felt incredibly realistic? Akio, a teenager who despises the latest hyped game, Three Realms Online, undergoes a twist of fate when his father entrusts him with a developer's testing copy to play and encourages him to give the game a chance. Akio's father, a lead developer of the game, has dedicated years to this project and desires for Akio to experience the 'life-changing game' he helped create.
What could possibly go wrong?
