The Show’s Overview Youhei lives in harmony with his mother Kaho and cousin Fumika. One day, Kaho tells Youhei that she isn’t his biological mother. Despite the fact that this depresses Youhei, Kaho assures him that nothing has changed and that he is free to live with her and Fumika, whom he has always treated as a sister. Next door, however, a woman claiming to be Ikue, Youhei’s true birth mother’s younger sister, enters and invites Youhei to join her. While Youhei is perplexed, the three women attempt to seduce him.
