I can't remember the tittle. Please help me find it TvT . I remember the guy is over 25+ in age and still jobless. He feels like a burden unlike his successful sister. One day he received an email? To test a game that was still on development. It was a building a kingdom game. He mentioned how the graphics felt real and the character feels alive because they are! Soon he was treated like a god for helping the people and protecting them. The in-game character even able to send the unique out of this world stuff to him in real life as gratitude, his mental health improve and he soon get close to his family again. The story progress and he found out there was another player but the player plays as the monsters n Demons leader to raid Kingdoms and killing thousands of people for irl money.
