A good-natured old man rides the waves

This is a story of an old office worker who is called "Good-natured old man" by his colleagues. He loves to be called like that. He strives day and night to keep his impression unchanged.

This is my original story which wrote in Japanese and translated into English. If you find some strange sentences or you can't laugh even once, you should better send a request to Google to improve their translator.

I would appreciate it if you could give me some advice to improve my English sentences.
