"I can't believe you did this!" Caroline yelled, running down the stairs, quickly facing her boyfriend who was silently drawing on the couch.

"You have to be more specific than that, sweetheart. I have done many things." He says, putting down his things on the coffee table. He looked up to his girlfriend, whom was seething. Oh No, he thinks.

"Oh, Don't act innocent with me, Niklaus!" She tells him loudly, using his full name. This was serious then, he thinks.

"I honestly don't know, darling." He stands up, and goes to her to wrap his arms around, to try and calm her down. But she moves away from him before he could.

"How many times have I told you not to leave your tooth brush on the sink?" She asks, holding up his tooth brush.

He lifts an eye brow. All of this for a simple tooth brush? god, he thinks.

"Caroline?" He ask warily, moving to her slowly.

"WHAT?" she yells.

"Breathe."

She inhaled and exhaled, calming herself down with every breath she took. Until she felt a pair of arms wrap themselves around her waist, his lips kiss her hair, and his shin lay on her shoulder.

"Your OCD's showing, sweetheart." He says gently in her ear.

"I know, I'm sorry." She whispers guilty.

"It's okay." He rubs her arms reassuringly.

"No, it's not." She turns to him, facing him directly. "I'm needy, insecure and sometimes suffer from extreme OCD."

She looks down for a moment. But when Klaus lifts her shin with his fingers, her eyes were watery.

"Caroline…"

"I'm afraid you're gonna leave me because of it." She says so softly he wasn't sure he heard her. Then a tear escaped from her eye. He pushed it away with his thumb.

"I will never leave you, Caroline. I love you. Everything about you. And when you're like this, I love you more. You're the best thing that's ever happened to me." He says, looking into those blue eyes of her.

"You promise?"

"I swear it, sweetheart."

She wraps her arms around his neck, kissing his neck the way she knew he liked it. "I love you too, Nik." She whispers, and he could feel the heat of her breath his neck. It was the best feeling, but not as good as her lips on his. So he kissed her, cherishing this moment and looking forward to an eternity with his neurotic, insecure, control-freak girlfriend whom he loved more than anything in this world.
