１リットルの涙, One Litre of Tears
This drama is based on the real-life struggles of a 15-year-old girl named Aya who suffered from an incurable disease, but lived life to the fullest until her death at 25. The script is based on the diary Aya kept writing until she could no longer hold a pen. The book that later followed entitled One Litre of Tears has sold over 1.1 million copies in Japan alone. Aya Kitō proved her courage and positive attitude towards an uncertain future when suffering such an illness, spinocerebellar ataxia. The drama spans a decade, during which she graduates from school while her conditions worsen.
The story begins as Aya prepares for the new semester. Despite being happy, she suffers from slight physical problems, which only her mother seems to notice. However, one day, she falls unconsciously on the floor.
After she is sent to the hospital, she is shortly diagnosed with the disease. Despite the fact that she is diagnosed with the terminal illness, she does not lose the will to survive.
She still makes friends with others, including her first love, Yuji. She later develops an interest in Haruto. Although somewhat cold, Haruto was still kind to her. Meanwhile, her health continues to deteriorate.
Knowing that she will not survive for long, she returns the gift Haruto has given, who discovers the fact when he reads the love letter that Aya gave him.
In the last episode, she dies peacefully, and her parents mourn her.
