Love Means No Need to Apologize

I just finished reading a novel "Love Story" by Erich Segal. It's an old novel. I found it among my friend's books collection. He and my other friend told me that this novel was legendary. They even made a movie and a song based on this novel. Too bad I haven't seen the movie nor heard the song. Like Reading Light said don't judge the book by its movie. So reading the book should be much more fun.
After I finished reading the novel it reminded me about one of Japanese movie "Sekai no Chuusin de Ai wo Sakebu". Although it's not exactly the same but I can feel some resemblances. Both of the story ended up with females death by leukemia. The title of this post was a sentenced said by Jennifer Cavilleri when Oliver Barret apologized for what he said before. This sentence also used by Oliver Barret to end the novel and cried in his father's arm right after Jennifer passed away. I didn't know for sure whether Japanese made that movie based on this novel or not. This novel came up first and it's a very popular novel. Sold over 21 millions books worldwide. But that doesn't mean the Japanese copied it. Well even they did I'm not gonna judge it.
Love Story is a story about a couple. Two university students got married and lived a good life until that moment came. This what makes Love Story is different from Sekai no Chuusin de AI wo Sakebu besides it's background. Sekai no Chuusin is about high school students. Their love would be more like a fling. Surprisingly in Sekai no Chuusin the man is always obsessed with the girl years after her death.
I wonder are there any such love? I've been in love. I experienced sadness too but it didn't take years to forget that sadness and find a new one :D May be because I'm not mature enough but I think there's a positive benefit with that. So I won't feel so down in such a long period. This is very important ability too :D
