I have a good working companion(coworker/colleague).
Yesterday, we enjoyed eating pizza and pasta at a sports-bar, and we played table tennis.
Then we went to a karaoke (place/parlor) to sing songs.
It costs money, however it was a very happy time.
I thought that there might be sometimes such time.(Don't really understand this)

Today, I worked with my companion for four hours.
It is good approach to work with someone, because if I feel loneliness, my motivation for working is dropped. (this entire part sounds strange, not really sure what you're trying to say)
My plan after now later is to cook dinner and do the duties that were left.

I tried to edit this in a way that still retains the style you wrote it in, but making it sound natural and correcting grammer. 

10/13 Good Job

It costs money, however it was so happy such a fun time.
I thought that there might be sometimes such time.  I was hoping I would have this kind of experience when I was working.
