Love at first sight

This story takes place in a city. A man moves in and falls in love with the woman who lives opposite to his apartment. I think the time is about 40 years ago because the man uses typewriter to write a message. the conflict is him vs other person. I think the climax comes where woman was thought she has an boysfriens, she was actually blind and the man which the main character thought he was  the women's lover, was helping her with daily life. There were many symbols in this movie,the bell ring, I think this is the symbol of joyful or blessing. a window and the curtain is the obstacle that he needed to come over. the irony is that she didn't actually have a boyfriend. the theme to this is that love is in-expectable. you don't know what's going to happen!!
