Your situation with Levi was...complicated. He loved you, he was head over heels for you, but you was his Cadet...and if anyone would know about his feelings for you, he would be in big trouble. Whenever he was with you, his heartbeat sped up, but he hid it behind his usual indifference, and aloof behavior. But if someone even looked at you in the wrong way, he shoot the poor soul a glare till they feel uncomfortable and turns around, so they won't see Levi glare that could kill. He knew that it's wrong to have feelings for his Cadet, but he couldn't help himself...he was already obsessed... The problem was the age gap, and that you was Erwin little sister. I mean, he doesn't really cared about the age gap, but he didn't wanted Erwin to find out about his feelings, because if he does, Levi could lose everything he ever reached in the Regiment...his title, the Soldiers respect, his team... you. Today the Levi squad is cleaning one of the old buildings, and as Levi wipes off the spider net's of the wall, you cleaned the dirty windows, scrubbing them to get off the dirt.

he watches you the entire time, he was fascinated by you...your moves, the way you look, your smile...that damn sweet smile, it's always driving him crazy...but he needs to focus on his duties.

Levi: He cleared his throat and scoffs "Don't scrub it too hard, brat. You gonna break the glass."
