ライオンのおやつ

The "Lion's House" is the name of a hospice located on a beautiful island. The people who live there are people with a short life expectancy. Shizuku, a 29-year-old who was told how long she had to live at a young age, comes to live there. She feels a little regretful over not being able to improve her relationship with her family before coming. At the "Lion's House", snack time is a time where the residents are allowed to request a snack from their memories but Shizuku is unable to choose. The days of laughter and tears begin alongside the other residents. What does Shizuku find and leave behind in the last days of her life?
