The ‘BEST FRIENDS’ is the idea of a sensitive love relation. It’s all about yours and mine pre-maturity, and after that how we grow, and then our matures-relationships.
Generally, the pre-matured love is a type of attraction, which might be a Mirage, and in future it’ll break down, but sometimes this love grow with yourself and it upgrade to the Matured love. In this case, the first possibility is genuine. But, actually the idea is all about your matured relation. It’s about two best friends, who generally didn’t meet with each other so much, but still one of them fell in love, with the second one.
The ‘Best Friends’ also raises the question, that how can a person fell in love, with another, whom he/she didn’t see before. Actually, in today’s life the social networking sites are a big reason behind those type of love affairs. you meet them through it, and by the time passes, they will become non-partable part of your life.
