Cyborg She (我的機械人女友) is a 2008 film out of Japan. The movie stars Haruka Ayase and Keisuke Koide.
Koide plays Jirou, a college student that seems very lonely. Jirou buys himself a present on his own birthday in 2007 and bumps into a girl in a Cyber suit. She tracks him to a restaurant and they have a fun night out together. But at the end of the night, the girl disappears in a flash of light in a tunnel. Fast forward a year and Jirou is again celebrating his birthday alone in 2008. But a Cyber suit girl shows up again and saves him. The girl is a cyborg and sent to protect Jirou from the future. Jirou develops feelings for the Cyborg, but things don't go well.
The movie was really a hard watch. Jirou wasn't that likable of a guy. Jirou was kind hearted, but generally a normal person that I would find no interest in. But the story revolves around him and the cyborg. Which never hooked me. Maybe that's why it took so long to watch it. I'd pass if I were you.
