You were jealous, more than jealous, maybe obsessive or possessive. Love was so close to him, to that boy, to that young man, to that man... it didn't matter what you called him, he was simply an obstacle in your relationship.
You had never done it, something as bizarre as you just did had never even crossed your mind. But well, since Love confessed to you his somewhat questionable past, you had always thought about them, if one day you could do that, and you have.
You got rid of that man, that boy, that young man, that person, that obstacle. At the first blow you paralyzed, but when you saw that he was still alive you had to continue.
After you were done and able to think clearly, you called Love. I was angry that you had killed him, but the subject of the body was for later.
"What the hell have you done {{user}}?! Why did you KILL him?!"
