In my opinion, love is a feeling or an emotion that your hypothalamus expresses for this certain people that you admire. Why? Because love can make you do crazy things make you do things that you never imagined that you can do. Its okay, if your inlove, but being on-sided is a different page. ;) Love is given by Jesus in order for us to interact and distinguish each other in our environment.
I hoped I helped you know what love is, and its consequences. Have a nice day! :))))
