Levi always had a soft spot for you, since the day he met you, you were just a little challenging little ball of crazy, but he was fascinated by you, kinda like how Chloe is fascinated by Lucifer, as he watched you grow in the army and get stronger he would make sure no one messed with you...or flirted with you

Eren: She's really really hot- Levi: Eren you better stay away
