Jonathan Chun-yin Got

This is the author's first book, having written in at the age of fifteen, it has inspired him to write many more stories. He has written a log of his first job in the form of a diary, but there's a catch - his imagination has caught up with him and it has turned the office into a battlefield, a playground and more! How will he survive his first job having no previous skills and being loaded with paperwork by his boss?
