A true story of Chie and her boyfriend Taro, and the love between them that sustained Chie through her battle with breast cancer.
Chie (Nana Eikura) is a ‘companion’, a young woman hired to speak in a public-relations role at corporate events, who ends up in the wrong auditorium. There she encounters a young salaryman, Taro (Eita).
Their relationship proceeds quickly, and soon Taro is talking of marriage. Chie, however, is hiding something: she has been diagnosed with breast cancer.
When chemotherapy causes her hair to fall out, she ends the relationship and moves away. Taro finds her after she has lost a breast to surgery; he insists that she is still the same person she was, and that his feelings have not changed. The two promise they will stay together no matter what happens.
