I have watched this JDorama a couple of times & it still makes me cry whenever I watch it. I can still watch this JDorama over & over again. I really love the story & it makes me love Hikaru ( Hideaki Takizawa) even more. About the ending scene, my interpretation about the said ending is that Michi is already out in a coma & and was just falling asleep when Hikaru return to the hospital. That's the reason why there is no more machines connected Michi. When she wokes up & saw Hikaru beside her, she holds Hikaru's face & he open his eyes & saw Michi's awake. Right at that very moment they knew they are already free to express their feelings to the world.
