Answer:
I consider that a love story fits perfectly there. The main story could be about a woman that met a the love of her life in a coffee shop.
He was rich, she was poor and they fell in love. Everyboday was standing against that relationship.
They used to meet in the same coffee shop they met for the first time. Lot of things happened, the man's family attempted to murder her. The woman's famility tried to kill him. Etc.
At the end, they had to scape from the city, and neither of them never went there (to the coffee shop) again.
