First of all is only about Sanskar and Swara (so no Laksh and Ragini) and they live in Mumbai.
I'll give you a background/prologue.
Swara is a doctor. A day while going to the hospital she meets an accident and goes in coma.
3 months later, Sanskar who now lives in swara's house is coming back home after work. He is an engineer. When he opens the door he finds Swara sitting on his sofa. He gets shocked to see a girl in his house. Swara on the other side gets a shock as sanskar can see her. She tells him her story. She went in coma, but her spirit is out of her body. She can do whatever she wants, but the problem was that no one could see her. He is the only person able to see her.
Sanskar decides to help her interact with her parents. Eventually doing that both fall in love with each other and confess their feelings.
One day while both are talking sanskar notices that swara's spirit is starting to disappear, but cant explain it until she leaves him.
He is heartbroken, swara left him forever.
After some days he receive a phone call from the hospital. It's shomi, swara's mom who informs him that now swara is out of coma.
He rushes to the hospital. Swara is still weak, so she cant open her eyes yet, but now she is out of danger.
He goes to meet her everyday, he spends some time with her talking about the time they passed with each other. Finally after a couple of weeks she opens her eyes and she finds sanskar sitting in front of him. His happiness has no bound until swara asks him: "who are you?"
Well sanskar quite expected that, swara doesnt remember anything, doesnt remember their love story, the time they passed together.
He smiles and leaves from there without saying a word.
4 years later:
Sanskar decided to leave India and settle down in UK. But now for work he had to come back in Mumbai for sometime. He still hasnt forgot Swara, but swara on the other hand doesnt remember him.
Will destiny bring them together once again?
So hows it? Should i continue?
