For comedy, I recommend History of the Salaryman. I love the female lead, she's fierce and very different from the usual ones. The plot balances some corporate drama with comedy, and I really enjoyed it for the most part. I felt that towards the end, things got a little more crazy and dramatic, but overall it was a very good drama and the comedic parts of it were the best.
As for romance, I would recommend Queen In Hyun's Man. I know that it has a similar basic premise as Rooftop Prince (which I did not watch but read the recaps of), but the feel and characters of both dramas are actually pretty different. Queen In Hyun's Man had little to no cliches and the male lead was a genuinely nice guy (something that is rare in a most romcoms). The chemistry was sizzling and the entire drama was executed pretty nicely.
Another one I recommend is Let's Eat - it's a mix of slice-of-life, comedy, food, mystery, and romance (later half of the drama).
