Rich guy act as a poor and fall in love with heroine.like OFFICE GIRLS...

hi can anyone suggest dramas similar to office girls. Rich guy act as a poor and fall in love with heroine.

I Second Fall In Love With Me.I thought rich guy acting poor would be quite popular but that is the only one i've watched that fit's that category. 

There's also:  Me Too, Flower!

I love this theme as well, but unfortunately there doesn't seem to be very many of them... :(
