After losing her lover, Linda's sadness drove her to reckless thoughts. I want a child. If possible, a black-haired one, just like my lover. Or else my heart is going to rip apart... Obsessed with this, Linda had her brother find an anonymous sperm donor, and she gave birth to a baby boy. Now a single mother, one and half years later, Linda meets a new potential lover: Nick, a friend of her brother, who is wonderful at housework and raising her son. But is everything that he is doing just glorifying Linda for "courageously raising her late lover's son"?
