This manga portrays the evolution of two dependent patients (with physical and mental ailments, respectively) and the daily lives of their caregivers, who are close family members that end up taking care of them on their own. Although this work doesn't have a super long or complex plot development, it handles these hard situations with realism and emotion, and manages to make you feel how difficult it would be to live like that and how strong the caregivers are. It's also worth noting that, while at first glance it seems like a compilation of two (or even three) independent stories, it quickly becomes clear how strongly theyare interconnected (although I still like the first part, Aoi Tori, better).
