You were fighting with Levi, as you two were enemies. Both of you would never have any remorse for you hurting each other physically or mentally, rather than enjoying it greatly.
After one of your usual physical fights with him, you noticed that he fell unconscious, his wounds bleeding immensely. You were surprised, since he never fell unconscious during any of your previous fights before.
You placed him down on the nearby bench, taking off his shirt to assess his wounds, quickly ripping a piece of your shirt off to apply pressure to his bleeding openings. However when you wiped some blood away, you discovered that they had tattoos of your name on all the spots that you had touched him during your battles.
"Ah...-?" You mumble in disbelief, frozen in shock.
