Plot device, plot device everywhere.
It's not even about character development, it's just about stuff droppin' here and there to make fall and bump into each other.
I've started Yesterday wo Utatte after watching 4 of the 6 episodes released because the premise was quite interesting... right now, i have the feeling i'm wasting my time on it.
It was such a decent base to works to and tell us a good story... then... that.
