Plus the seiyuus will be the people from the actual drama!
ANN: The drama follows two childhood friends — a boy and a girl — and the tragedy and angst that befalls them and those around them in the years between high school and young adulthood.
(Drama, Romance, Angst, Tears: Definitely my kind of anime!)

OMG the character looks like Bae Yong Jun (doh!) It's awesome! I wonder whether it's going to be in Japanese? Maybe Korean language with Japanese subtitles? Nevertheless, I'm excited to watch this!
