So...no more hundred days left to live? Did the main story just end?
I'm gonna miss the mystery aspect where everyone was tripping over themselves trying to find out how the number countdown worked, what the death would be, what caused the fluctuating number...not to mention the juxtaposition of a happy couple and a lively group of friends balancing light-hearted humor and grim undertones of looming death. That part, done so well in the covers where a happy Umi is in front of a somber and often darkening background with the number decreasing, was what made the manga for me.
Now that there's no hundred days and no looming death, all that's left is...memory loss? The stakes don't seem too high here. Either way I guess I do wanna see what'll Umi do to win Tarou back and start being decisive and direct in her actions as opposed to "I want to make everyone happy or I'm scared they'll leave me." Could be a chance for more development for her.
