Our MC is a common University student, perusing his bachelor's.
One day he installs a new app on his phone.
It's description read
"Create your very own world & explore various mysteries, all to your heart's content."
This app changed his life, and in ways he never believed possible.
He saw as many things you are inclined to believe and just as many things you might have never thought of.
Come and join in his journey.
Oh! And the name of the app you ask?( well look at the at least man) it is the World Creator App. Surprise! Surprise!
