April Bride

April Bride is the final testament of Chie Nagashima: the word is “love”. 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 salary man, 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. (official distributor synopsis)
