Kakushigoto is really good.

It is the story of a single-parent manga artist who is ashamed of his work and goes to great lengths to keep it from his young daughter.

The story begins when the girl, now older, discovers her Father’s job, and is told through flashbacks to her growing up and life with her father who was always trying his best for her.

I can’t find the official trailer with subtitles but it gives you the idea. Trailer.
