Matriarchal Romance, Both Leads Pure, Sweet Story

Looking for books like *After Transmigrating into a Matriarchal World, She Spoils Her Unlucky Dark Guard Rotten*. I want a clean, one-on-one romance in a matriarchal world, with both leads devoted to each other! The heroine can’t be a flirt who treats everyone the same! Thank you, thank you, thank you! I’m seriously out of books to read (╥_╥)
