I had to look at my shelves for this. It’s seems to be recurring thing for the most part. In my stories with a Alabama Crimson Tide Still not tired of winning shirt, there’s one where the love interest is very prominent in the story, in the other, the love interest is carried as a crush for three books and left off at him getting rejected so there basically wasn’t any love the whole time. Media seems to love their romances so if want to have higher chances of a bestseller do that. If you don’t feel that a romance is important or necessary don’t put it. Really depends on you.
