I'll impregnate a human male, give birth to a child, and then come back! Go Yumin, the eldest son of the endangered suwin (human-lynx) "Black-Footed Bobcat" family. Having never seen a female his own age, he's been forced to live a single life since birth. Just as he was entering heat and nearly driven mad by the desire to breed, he heard a secret rumor: "Male bobcats can mate with human males and can get them pregnant with absolute certainty."
Determined to have children, Yumin infiltrates Korea University in search of the most handsome and intelligent man. There, she meets Beom Taejun—a man with a charming face and a seductive body. Yumin sets aside her pride as a lynx and tries her best to seduce him. However— "Go Yumin… hff… I'm going crazy because of you." "No… ahh…!" When she regains consciousness, she finds herself lying on Taejun's bed, being toyed with and abused. "Oh my… so I'm the one who's on the receiving end of a pregnancy?!" Despite her best efforts to free herself, her body slowly becomes addicted to the pleasure Taejun provides. Will Yumin be able to finally conceive a baby lynx to continue her family line?
