Insert a Catchy Title

Do you remember the guy who was only a year or two older than you and also was the brother of your bestfriend from childhood, who used to butt into you and your best friend's fun time just to annoy you when he was bored ?
That's exactly what Dhruv was to Navya- the ever present third wheel and the neighbor who you'd fight with from your room's window.
Then, they grew older- parted ways and went to pursue their own fields of education in various parts of the country/world.
Now, after years they're back home but the mutual annoyance they have for each other hasn't ceased to exist.
What exactly traversed between them after their return that made them fall for each other is a huge series of events that needs a nice full-length novel and that's what you're about to (maybe not) read.
