The truth of an unacceptable kidnap crime reveals after 15 years…

What is LOVE? If their love is so quirk and doesn’t meet the social expectations, why they can’t just simply get together?

Sarasa Kanai is the nine-year-old daughter of a free-spirited couple who met at a music festival. Her parents always treat her as an adult and the three of them have a lot of in-jokes. Sarasa is happy even though her classmates think her family is strange. However, when her father suddenly dies, her mother leaves and Sarasa is forced to move in with her strict aunt and uncle, as well as their teenage son who starts sexually abusing her at night. To avoid going home after school, she spends more time at the playground where she regularly sees nineteen-year-old university student Fumi Saeki.

On a rainy day, Fumi offers her his umbrella and she tells him she doesn’t want to go home. He invites her to his apartment and says she can leave whenever she wants but Sarasa ends up staying with him for two months. They watch the news of her disappearance on TV. The two of them form a close bond as Fumi, who had been controlled by his mother for years, begins to loosen up. He admits that he likes young girls but Sarasa feels safe with him and he never touches her. They go to the zoo but Sarasa is recognised and the police arrest Fumi for kidnapping a minor. Sarasa panics during questioning and doesn’t explain Fumi’s innocence. Unbeknownst to Sarasa, Fumi is diagnosed with a testicular disease that means he never went through puberty, leading to his conflicted feelings about young girls. Videos of their emotional separation at the zoo go viral and follow them both for decades.

Fifteen years later, Sarasa is twenty-four and a waitress at a chain restaurant. Everyone knows about her past, including her boyfriend Ryo Nakase. They’ve talked about marriage but Sarasa is still uncertain. One evening, she goes with a colleague to a café, not realising that it is run by Fumi. He acts like he doesn’t recognise her but she starts going there after work, telling Ryo that she’s working overtime. She sees Fumi with his girlfriend and asks him if he remembers her but he walks away. Sarasa sleeps at an internet café then goes to work where she finds Ryo outside waiting for her. While they’re arguing he receives a call saying his grandmother has collapsed. They go to his hometown where his cousin tells her about Ryo’s history of domestic violence, but Sarasa vows to stay with him.

Ryo follows a website dedicated to updates on Fumi and Sarasa’s lives and realises that she has been going to his café. Ryo beats Sarasa and she runs away to Fumi who lets her into the café. While Ryo is at work, Sarasa gathers her belongings and moves into the apartment next to Fumi’s. Once things have settled down, Sarasa agrees to look after a friend’s eight-year-old daughter, Rika, and one night they have teppanyaki with Fumi. Later, when Rika has a fever, Fumi looks after her while Sarasa is at work. Her colleagues have also been following the website and then when Ryo writes an anonymous article about Sarasa and Fumi, the exposure is too much so she leaves her job. She confronts Ryo and he tries to grab her, but he falls down the stairs and needs to go to hospital.

The police bring Sarasa in for questioning where she finally explains that she was abused by her cousin and Fumi was innocent. Rika is fine and goes back to her mother. Fumi’s girlfriend leaves him when he explains his conflicted feelings about young girls. Sarasa and Fumi stay in a close relationship with no sexual intimacy, moving towns each time someone discovers their identities.
