Aonaki Kayo is an otaku who's very good at games.
After his death he's reincarnated in a game world and he uses his intelligence and game knowledge to "win" the game.
He learns something, though.

While games have a clear goal, life in another world doesn't. Maybe he's the one who has to set the end goal, maybe the people around him will inspire him more than a game character.

The story of a journey -- not only a physical one.
