It's been a few weeks since she entered university.
One day, when she came back home, she stumbled upon a man she didn't recognize.

He had previously been her computer.
The reason he gave for wanting to become human is that he "wanted to have fun"?!
Was that really all he was asking for?!

This is the story of a computer, who had been allowed to remain human for just three days, and its master, the protagonist.
