I might add to this, I don't know. Not much of a storyline here, just floating out in the deep space of fanfiction. That might change at some point.
"I am in love with you, and that's not good because you're evil. How do I know the next time I hurt you, you're not going to try to kill my friends, or try to kill me, or compel me to do whatever?"
"Because I'm not like that, Caroline! Don't you see, I want all of you. The sexy control freak, the shrew, the princess of Monaco, the woman that screams at me. I don't want you to coddle me and tell me you love me just so our relationship stays safe and I don't go on a murderous rampage. I want you to be there when I am in the thick of it and knock some bloody sense into me!" Klaus replied. Caroline stared at him.
"You know, I didn't use to be pure evil, I didn't use to hold century's worth of grudges and love that monsters were afraid of me. I used to only want to be happy with my family and do what makes me happy. I had to have my heart broken so badly that I became something I didn't even recognize in a pool of water. I've been this way for a thousand years, love. But you changed me back, and I like being the good man, especially for you." Klaus took a deep breath and stood in wait for Caroline's reply. She looked away with a small smile, and then gazed back at him.
"You think I'm sexy when I'm being a control freak?"
"Sexy as hell, Caroline." He replied easily. Caroline laughed and threw her arms around him, crushing her lips to his. His surprise was so great when he caught her he didn't even realize he was falling to the ground.
