Turn left turn right

This movie is actually called "Turn left turn right"

A man who lives on the left hand side of the building is a violinist. A woman who lives on the right hand side of the building is a translator/writer. They take a different route to work in a big city, where people never say hi on the street to each other.
The man and the woman both feel lonely and depressed in the big city because they have no one else. One day they meet in the park and talk extensively as if they are old friends all their life.
Fate intervene. Rain smudges their phone numbers so they can never contact each other after that day. They wait in the evening for the phone to ring, but it never rings.
They get on with their normal life. The woman celebrates her birthday by herself, with the guy playing violin in her honour, but they don't know they are neighbours.
They meet again in the New Year's party, and discover they are next door neighbours. ^_^ It's a story about a big city where people who doesn't care about other people, and feeling lonely while so many people are beside you. You feel lonelier when there are people surrounding you because they don't know you and don't care.
