After Taming Beasts, I Became the Campus Goddess

Detective Conan!! Female Protagonist!! Something Good!! Please!!

An Old Story I Read Ages Ago: The Female Lead Was a Beast Tamer, and the Male Lead Was Incredibly Powerful

The heroine's family doesn't love her and abandons her in a forest. By chance, she makes a pact with a spirit fox. The hero hits a bottleneck while trying to break through, forces himself on the heroine, and successfully breaks through. He's incredibly powerful and treats her really well. I really can't find the book, though.
