Sierra Delight, heiress of the Black Panther Clan. Due to the biggest mistake of her life, she ends up in an arranged marriage with someone far beneath her in status. Her partner: a member of the Rabbit Clan, known for competing with the Squirrel Clan for last place in the Beastmen’s Tournament. —“Fine, then! It’s going to be divorce. I’ll make sure there’s no other option but divorce!” With a reluctant heart, she enters the bridal chamber… but— —“Haah… Calm down a bit! Damn horny rabbit!” —“…It’s our wedding night… our first… night…” The rabbit she thought was weak turns out to be way too strong and skilled in bed! By day, he’s an innocent, sweet, and gentle rabbit. —“I love how it feels to be inside you, Lady Sierra…” —“It’s so warm… I want to keep thrusting into you… it would be wonderful if we could just melt into one…” But at night… he turns into a lustful, rutting beast. —“…Was I tricked into marrying him?” Will Sierra be able to find satisfaction with her rabbit husband?
