Miporin's Dimple.

Hirosue and Nagase will play a married couple in this tearjerker, based on a true story of two parents who are told that their daughter Miho (played by Manatsu Kimura) has one year left to live due to a brain tumor. The drama depicts the family's remaining time together, including the 359 letters that Miho drew before her death. --Dramawiki
