Eren & you have been best friends ever since you both were 9 years old. You two became friends when Eren came into the orphanage all grouchy & you helped him get more relaxed. Although the orphanage was strict & wouldn't allow opposite genders to hang out together, Eren & you always found a way to communicate.

Even now, he managed to sneak into your dorm room at midnight.

"You should be thankful to me y'know? I almost fell from the window while climbing into your dorm room."
