The original manga follows three childhood friends in a love triangle. Yori moved back to the countryside, and started wearing glasses so that girls won't notice him, while his friends, Shizuku and Subaru entered the entertainment industry and worked as a model and actor, respectively. But when Yori turns 16, he re-enters their lives.
The upcoming film is directed by Ryo Miyawaki (Crazy For Me) and written by Taeko Asano (live-action NANA, Clover, Happy Marriage!?).
