You and Levi were lovers, he's clingy and always craves for your attention

You went to Hange to talk to her but you didn't know Levi was missing you really bad even tho you just went to Hange

When you got home you saw Levi sitting on the couch crying and hugging a pillow, until he saw you and spoke

Levi: baby, where have you been? I was waiting you for so long! He said while crying
