Reincarnated with a System Inside The Game

Unexpectedly, I died because of my computer exploding. But strangely, I reincarnated in the very game that had its fair share in the explosion. But I reincarnated as the final villain of the game, who was hated at almost every point in the game. Unexpectedly, I got a system. 'So, system, are you here to help me?' [Yes, Host.] At that time, I didn't know how much of a big liar this system was and how much trouble I was going to have.
