Romance is definitely a secondary plot of the drama, if not tertiary.

I'm writing the review as I'm re-watching the drama as there are a couple of nitpicky things that bother me.
1. The marketing team is in charge of development, working with production, and all the other things. ??? Why not just call it The Team as they seem to be doing it all.
2. Director of the headquarters, what sort of title is that? It's the label on 옥자정's office but she's Director of marketing (see rant above). As there is barely an office scene without showing it it's annoying me more and more.
3. There's the main cast that's the focus of the story, but there are at least 2 people in the same office space as The Team who are on occasion shown as part of the group but they don't otherwise get any acknowledgement or even a name. At one point there's a performance review and there are ~7 personnel files, but it's all focused on the main 4. Why bother padding the numbers if they aren't involved in any way whatsoever. Actually excluding these extras would probably make more sense and emphasize that this is a small business. Otherwise making it a marketing team focused only story would also make more sense.

It's still an enjoyable watch, even as a re-watch, but don't expect too much from it.
