HOLY SHIT!

IT ALL MAKES SO MUCH SENSE NOW

THIS EXPLAINS 4CHANS OBSESSION WITH ANIME AND ANIMES OBESSION WITH CUTE YOUNG LOOKING GIRLS

THANK YOU OP.

ok /sci/
why do people cheat?
is it because we are evolutionarily designed to multiply as much as possible?
are we all polyamorous at heart?
is it too easy to attract someone by saying or doing the right things, regardless of whether they are single or not?
the thrill of the unknown/getting caught?
I'm struggling to understand it... perfectly good people fucking up perfectly good relationships.
see if you can provide a scientific explanation.
