she falls in love with her bodyguard but they can't be together so she asks him to marry her in secret.
I suppose they were suppose to meet at a place, he went there by motorcycle and she by foot, but he got an accident (he died) and as she walks towards the place of meeting, she sees the scenery of the accident and she finds a ring and she understands he died.
Then she walks further until she falls on the ground and there she is, left alone, crying. and the love of her life is dead.
.... that's how I see it at least
