Its not super hard to see whats going on behind those cheeky smiles which mean exactly the opposite than they were intended to mean. While on the other hand some people are so plain and simple that you have no other way than to fall in love with them. "Life is like a box of chocolates, you never know what you get". (Forest Gump).
Perhaps not everyone does fall in love with them ofcourse people are demons and they only love demons. I wonder if demons too bite each other or they only get humans to bite... Question of the day??
