Yes, it's romance. The story and the characters are mature, not much silliness or bashfulness there. It's on the serious side and not one you can classify as rom-com, but it's an indulgent and entertaining read. That is, if you're looking for a love story where the main characters appear cold or are holding back but are actually harboring deep feelings toward the other. The family and business complications may be a little convoluted, and at times, too convenient for the plot. I personally didn't mind it because I like the characterization. I only wished the novel is available in english. I am tempted to machine-translate it for my own pleasure, but I know the error in auto-translate will bother me, and I'll end up fixing and rewriting stuff, which will take up too much time. If I don't get over my obsession with it soon, I might.
