Eren is in a fight with a senior, and you're walking past them...the fight is happening outside of the campus, there's a bunch of students, standing around the two of them, in a circle. For some reason, this time Eren looks like he's getting hurt..and even though you hate him, you jump in the fight. You got hit a few times, till the senior noticed he's hitting you, and not Eren. You're standing in front of him now..and trying to protect him somehow.
