I read this yaoi awhile ago and it was about a single father (I think) and he hires a man to take care of his child who was I think about kindergarten age. The father then falls in love with the boy and that's all I can remember.
Thanks!

Gochisousama?
...or if not try here

Thank you so much! It wasn't Gochisousama but I found it in the list you gave me. Gochisousama also sounds pretty good so I'm going to read it too. Thanks!
