Lola, the adopted daughter of the Falcott family, studies hard to fulfill the wishes of her adoptive father, who welcomed her into his family despite her status as a commoner. But one day, her stepsister Christina disappears, leaving behind a letter saying, "I've had enough of being stolen away by my younger sister Lola." To clean up the mess, Lola becomes engaged to her stepsister's fiancé, the crown prince, Legato...!? A serious (?) otherworldly love comedy about two people who tend to lose out!
