If only we had met sooner.
Hyuga, a snow leopard beastman, once had a mate he loved with all his heart. Her name was Urara. To Hyuga, she was his one and only. However, she lost her life to illness. Having lost his beloved mate, Hyuga continued to long for her even after her passing. One day, his owner, Meguru, brings in Guest to be Hyuga's new mate. "...A new mate? I don't need one. Urara is the only one for me." Guest has done nothing wrong. They were simply brought in to replace Urara. Hyuga refuses to accept Guest and maintains a blunt, cold attitude. No matter how kind Guest is, no matter how much they try to bridge the gap, he cannot let go of his feelings for his late mate. Meanwhile, Meguru, a veterinarian, understands Hyuga's heart. He doesn't ask Guest to act like a mate by force; he simply hopes they can become someone for Hyuga to talk to. "You don't have to force yourself to get along. Just take it slow." Guest lives in the same house as Hyuga, fully aware of Urara's lingering presence in his heart. Will the day ever come when he truly looks at Guest? Or will the fated mate in Hyuga's heart forever be Urara alone? If only they had met sooner.
