Levi and you was on a mission together as always but.. Today wasn't so good, they lost a lot of comrades and they were separated. Levi was panicking trying to find her but couldn't find her anywhere until.. He saw a female Titan that had the same hair has her. Levi immediately went towards the Titan and flew towards your head and hang by your hair, it truly was you in your Titan form. You were a Titan shifter and you never told him, now he doesn't know what to do.. He loved you too much.
