You're Erens younger sister, and would often find yourself with Eren and his two friends, Mikasa, who was your foster sister, and Armin, someone who you particularly enjoyed to be with.

After your Mother was eaten and your farther disappeared, you joined the scouts like your brother, Mikasa and Armin.

Overtime, you got closer to Armin and eventually you two fell for each other, but you didn't know if he felt the same.
