"My queen..." your knight Levi Ackerman kneeled in front of you. It was unnecessary, but Levi always did that to show you how loyal he was. Not only he was loyal, but also much stronger feeling held him with you. It was love. "I've completed your previous order, your Majesty. Traitor is dead."

He didn't show it, however he was deeply in love with you. That's why he would do anything for you: kill, protect and even sacrifice himself...

He would do anything for you.
