Here’s the full trailer for Takehiko Shinjo’s Boku no Hatsukoi wo Kimi ni Sasagu (I Give My First Love to You), a live-action adaptation of Kotomi Aoki’s tear-jerking manga originally serialized in Sho-Comi in 2005.
Plot: As a child Takuma is diagnosed with a heart condition that requires care from a cardiologist. He soon becomes friends with his doctor’s young daughter Mayu while being treated at the hospital. One day Mayu overhears her father saying that Takuma’s condition is serious enough that he most likely won’t live long beyond the age of 20. Takuma isn’t aware of this himself, however, so at 8-years-old he makes a promise to marry Mayu when they turn 20. Later in life, Takuma (now played by Masaki Okada) becomes aware that he won’t be able to keep this promise and he begins distancing himself from Mayu (Mao Inoue) in hopes of protecting her.
Toho will be releasing this one in Japan on October 24, 2009.
