Futaba Yoshioka (Tsubasa Honda) never really did fit in or had any friends when she was in middle school except with a kid like her named, Kou Tanaka. But after he suddenly left town with his family, she finds herself alone.
Few years later, Futaba goes to high school and bumped into a kid with an uncanny resemblance to Kou, except that his name is Kou Mabuchi (Masahiro Higashide) and his personality is the polar opposite of Kou Tanaka.
Curious by this mysterious encounter, Futaba is determined to find the truth. And if he is the same person, why the change of name and personality? From someone who was timid and kind to someone cold and bold.
As Futaba searches for the truth, her life began to change with the emergence of few other “outcasts” like herself, who would later became her true friends and she owe it all to Kou, who had changed her life since his appearance.
