What makes you fall in love?

[Kibs]

To put it in a nerdy way:

"My neural pathways have grown accustomed to your sensory input"


Generally you spend more time with people you get along with, this eventually builds up a familiarity to the person which makes it feel as though it's "right" being with them.

Continue on with this thought process and that's the most unromantic way to describe love ever.

Yay, science!
