Milfa, an elf with blonde hair and pointed ears, marries the human Kenji amidst strong societal opposition and discrimination against inter-species unions. Her parents' absence from the ceremony underscores the deep tension between humans and elves. On their wedding night, Milfa and Kenji discover an anatomical incompatibility preventing physical consummation of their marriage, a challenge that becomes central to their relationship.

Despite this difficulty and the prejudice she faces living in a human town, Milfa remains committed to Kenji. Her pivotal moment comes when she rescues two children from a rampaging hydra, an act of courage that shifts community attitudes and earns her respect.

When Kenji departs seeking a solution, Milfa independently visits a gynecological clinic. There, she encounters other women facing similar physiological challenges, including a half-jinro and a half-hobbit. During the visit, the incubus doctor, Dr. Perio, assaults patients using illusions. Milfa resists his mental manipulation, headbutting him and breaking the illusion to reveal the truth.

Milfa evolves from passive endurance to active resilience, confronting societal prejudice and personal vulnerabilities while maintaining dedication to Kenji. The narrative concludes with Milfa and Kenji returning home together, their central physical challenge unresolved.
