I am the most exalted princess of the beastfolk, born to a prestigious status and showered with everyone's love. But my werewolf husband is devoted to playing games with stand-ins. He married me only because I looked like his first love. After our wedding, he remained aloof and self-controlled, famously following the Three Don'ts: Don't care, don't make a fuss, don't make a move. To get back at him, I found a stand-in who looked just like him, not only in his human face but also in his beast form: a young werewolf. The stand-in was young and strong, and loved the Three Moves. Moving this way, moving that way, moving together. Life went on peacefully, and we each kept to ourselves. Until one night, the stand-in knocked on my door. “Sister-in-law, open up. It's me, your brother-in-law.”
