introduce a movie

i I want to introduce a movie named "A Sad Story Than Sadness" , which is extremely moving.
The first time I saw it was two years ago and later on I saw it many times.
and There is a scene in the movie which i am totally crazy about.

that is When actress has to marry a man she does not love at all, the actor, who has the an incurable disease, just gives her a pat on her hand and turns back to go out leave of the wedding hall. He knows he will die so he hands her to another guy who can accompany her instead of him.

Every time I saw that scene , I had a feeling felt that something came into entered my heart---the truest love in the world.

I cant help crying.

From then on , I always like to pat my families and friends on their hand.
They all dont understand what im doing and they feel it is strange.
But i just smile and still pat with deep sentiment feeling.
This is my way to say "you are an important one in my life".

Please help me corret this article
and could you please tell me what sentences would you make if you want to express the same meaning?

你写的不错。绿色的是你写的对可是有点点奇怪，所以我给你建议其他的说法。

加油！
