Well so far I like both the romance and the story a lot so maybe a bit of both?
Especially since nothing so far really feel like filler as others have said
Like, you have the main story and instead of entirely different routes romancing someone just gets an extra line here and there aknowledging it plus a few small extra/alternate scenes.
Eg: days 1-4 would mostly be the same, day 5 change bc it's a date with the love interest or a friend outing. Then day 6 onward back to the main story etc.
P s. Maybe another option would be if you could have some help?
