They are out there chasing the wrong person, something you would call "unrequited love", which essentially means loving someone but not in a mutual basis.
They have a lot in common, in fact, their stories are synchronized. And they both found out that there are repercussions in love, the hard way.
Something didn't work out, and rejections happened. Rejections are always a potential trigger for depression. And by depression, that's far from spending a Saturday night watching reruns, eating your favourite ice-cream. Nope, they were broken, scratch that, they were devastated. Devastated enough to seclude themselves in an emotionally dark place.
Parallel scenario, they both lived the same story yet never meant. For some interventions, their world collided but they're both already shattered by the demise of their own runs.
That's is, until they found each other, but love is a deceptive thing..
Two lost souls found one other, both the ability to fill each other's attenuated gap... But would it ever suffice?
