A charismatic high school girl with a decidedly rainy day approach to friendship finds just how important connections can be when she is diagnosed with a terminal illness and relegated to a lonely hospital bed. Rina comes from a dysfunctional family and only contacts her friends in times of need. Her father is completely self-absorbed, and her mother is overprotective to a fault. One day, after discovering that she has a terminal illness, the girl who once viewed her friendships as disposable is forced to sit in her sterile surroundings with nary a friendly soul in sight: Her family is too wrapped up in their own affairs to drop in for a visit, and her friends all realize that she never cared too much for them in the first place. Much to Rina's relief, a concerned classmate named Maki eventually appears claiming that she and Rina were good friends back in grade school. When Maki tries to re-connect with her old friend and Rina realizes that she doesn't even remember the friendly girl, it soon becomes apparent just how flawed the philosophy of this fiercely independent teen truly is.
