Interesting story that contains a robot, but actually pulls it off. Maybe it's the cast and their great performances. Or the chemistry between the two main leads. Or maybe the theme that was interesting, entertaining and kind of touching with the leading man's story being a really heartwrecking one. The story in general is cute, though it does have it's chiche moments and some scenes were way too long. But, all in all, enjoyable and it keeps the interest high through the end so 8 out of 10.  Also the costumes were really cute too.
