>>21485230love the concept is real.
love as an emotion is not, emotions like anger, sadness, joy, they can all be measured and induced. you can test someone and see how capable of joy they are, if someone can't produce serotonin at all, for whatever reason, they're probably not capable of joy as you or I understand it.
it's possible to love, but it's not as if a wizard just zaps that emotion into your head. it's something you have to develop with time, and appreciation.
