My SSS-Rank Dragon Kneels for Me

Vivian is the only human female in a world of beastfolk—yet she fails every test, and her S-rank wolf dumps her on the spot. Then an SSS-rank black dragon breaks out of isolation, kneels before her, and begs to bond. Three suppressants can't calm his rage—her touch can. Her smug ex regrets everything, and a feral silver-fox hero melts in her arms.
