I Can't Believe I Can Bring Game Items Out

A fast-paced, feel-good gaming novel. I’m just an ordinary person, except I happen to have an ability that gives me a personal space. When the all-encompassing immersive game Second World arrives, the protagonist takes out a bottle of mineral water from his personal space and takes a sip. Then he freezes. W-Wait, is this inside the game? From then on, items from the game can be brought out, and items from the outside world can be taken in. The protagonist’s life is turned upside down.
