Yukie Kitahara (Sayuri Yoshinaga) is a housewife and she has devoted her life to her family. Mako Goda (Yuki Amami) is a wealthy woman who runs a business. They are both diagnosed with terminal illnesses and are told they only have a short time left to live. These two women from completely different walks of life meet at the hospital.

Yukie Kitahara and Mako Goda decide to carry out the girl’s wish list and they begin to feel happiness entering their lives.

(Remake of 2007 American film "The Bucket List.")

For those interested in the roles the girls played: One of the items on the bucket list was going to an idol concert, so that's what the main characters do. The scene was filmed at Momoclo's Valentine concert in 2019, so they're actually starring as themselves.

Ah, that's great to know! Maybe I should watch it sometime, I just haven't looked where to get it subtitled.
