Cowboy hat rule romance MMC falls first (and hard)

This is kind of specific, but I’d love a romance where the MMC sees the FMC and immediately falls in love, while she (preferably an outsider) has no clue. I’d love a premise where he keeps trying to sneak his hat onto her head while she doesn’t know the consequences of it. Alternatively, something like she knows the cowboy rule and goes out of her way to avoid the hat until she falls and then makes a big show of putting on the hat. I’d love to see a book with either of those premises, but I’ll take any “wear the hat, ride the cowboy” book I can get

Edit: I’ve read most of Elsie Silver’s books and enjoyed them
