From what I can tell from the first episode,
Unemployed Romance is like that. But it's a drama that just recently aired, so not many episodes have been completed yet.
Other than that:
Seigi no Mikata (very funny, light-hearted drama)
Who are you? (this drama isn't the same one on your list, but an older, different drama with the same name made in 2008, has body-swapping hijinks)
Ma Boy (a feel good, short genderbending drama for when you don't want to think too much)
