45-sai no Senkou Hanabi

Ichinose Hanako is 45, a full-time housewife living in a rural town. Despite daily frustrations, she lives a fairly happy life. One day, she sees her vocational school classmate, Mizuki Urara, appearing on television as a novelist. 27 years ago, the three of them, including another classmate, Hiraizumi Kanon, were hanging out together; she vaguely dreamed of becoming something, but Urara rejected her hopes and they had a falling out... What action did Hanako take, overcome by jealousy as she compared the past and present? A friendship that broke when they were 18 troubles the hearts of three people now 45 years old.
