Poison for lonely souls

What even is love?

"Fake. Overrated. Chemical reaction. Fiction for lonely souls. Also known as ~love~.
Such a weird word. Such a weird idea." says a mother, that's been left behind by the one who swore to never leave her, the father of the kid asking "Mommy, what is love for you?"
Why such an impulsive response for something so simple?

That "kid" grew up and is now a teen, a teenage girl to be exact. A pretty brunette with the eyes of a deep earthy colour, future Albert Einstein she says.
But this is all behind our point: to find out what even is love?
