This movie made me cry. It's one that confuses you if you don't pay attention, but at the end, it all comes together. Two thumbs up for this movie, that's all I can say. The following synopsis is taken from
MySoju.com, where you can find the links to watch the film with subtitles.
Description: One day, a beautiful cyborg girl appears in front of a dull university student. Even though the cyborg starts to like him, she can’t truly feel emotions, so the boy has no choice but to say goodbye to her inhuman power and ‘violence’. Missing her, he continues his lonely existence. Some time thereafter, a disastrous earthquake hits Tokyo, and the cyborg girl saves his life. In that moment, she starts to have feelings like a real human being.
