Midori, a sad and discouraged girl, is struggling to cope with the loss of her mother, who died when she was young. Her boyfriend proposes to her, but she's unsure about accepting due to her emotional baggage. One day, she buys "Seeds of Happiness" from a flower shop, which she plants in her garden. To her surprise, a girl named Nozomi grows from the seed, claiming to be Midori's mother, reincarnated in a magical plant form.
As Midori gets to know Nozomi, she learns about her mother's love and sacrifices. Nozomi helps Midori work through her grief and come to terms with her past. However, Nozomi's life is limited to one week, and she grows rapidly due to Midori's care.
As the story unfolds, Midori's feelings of guilt and regret about her mother's death are revealed. Nozomi, however, reassures Midori that she is proud of her and wants her to be happy. With her mother's blessing, Midori decides to accept her boyfriend's proposal and start a new life.
In the end, Nozomi's life comes to an end, but not before she sees Midori happy and fulfilled. The story concludes with Midori's wedding, where she is finally able to find happiness and closure, thanks to her mother's love and guidance from beyond.
