No, it's not okay to murder, to hurt, or to ruin but that doesn't matter to Harry, nor does it matter to Louis. They met by accident, an accident that doesn't even matter, but they know they found the right one because their favorite color is red and well, a few more things they have in common. It's a beautiful love. A very beautifully, dark, twisted love. A love people would kill for; gladly Harry and Louis do. Or the one where Louis and Harry are a "couple" of serial killers (Quite the famous duo) "The killer couple is a love everyone should envy"
