Help! What movie/drama is this?

I need help figuring out the title of this movie i watched a while back. I think it was a movie but it might as well have been a drama..

So the male lead makes a living dating girls, and the female lead writes letters for a living. They meet at a restaurant/cafe where they are both regulars and the male lead mistakes her for his customer and takes her out on a date. 

If you have any idea, I would be really happy if you could help!

 Six:

It's Romance Blue.  The summary on MDL doesn't tell you what each lead does, but that's the one you're looking for, I think. (I'm pretty sure the description is totally wrong, actually.)

Yes thats the one! Thank you!
