It's a beautiful love story (hey, I'm a girl so yes, I like love stories!) and its title is "PS: I Love You".
The movie is about a woman whose husband dies.
To help her live after his death, the husband writes letters that are supposed to guide her.
And there are flashbacks about how they met and fell in love in the first place.
As you can guess, I cried a lot, even if I know this movie very well (I have seen it a lot of times already). （Ｔ＿Ｔ）
I'm a very emotional person. I guess I can't help it. (^_^;)
