I really don’t remember much. What I do know is that it is not a recent series. I would say between 2012-2017, these last few days I have been going back as far as 2010 releases. It is set in modern day, it is a romantic comedy. There is a slight chance it might be a C-drama, but I have only recently started watching C-dramas.
The male lead was not rich, but had a good paying job, he wore suits. I believe he was kind of a workaholic and not completely socialable. Because he spent his time at work he hired someone to clean his place and cook dinner, but requested that they were not to be there when he got home. One day as the girl was cleaning, she wasn’t paying attention to the time and when the buzzer to the door goes off she panics and hides. She ended up hiding in a closet I believe over night.
As for the girl, I really don’t remember anything, except that she was really in need of a job.
There is most likely more to the series, but this is all I remember. I don’t think it was more than 25 episodes.
I am sorry that there isnt much more to go on
