Know what they say about identical twins, that there's always a good one and a bad one? Well, Ayumu and Atsushi seem to be proof of this. Atsushi is the perfect one – smart, kind, accomplished and loved by all, while Ayumu is everything but. Quite unexpectedly, Atsushi dies in a car accident. Ayumu is then transferred to his late brother's school and while there, he "becomes" his brother, playing the role of the good and kindly one while virtually obliterating his own personality in the process. But can he keep up the charade in the presence of the one he cares about?
