You are Reiner Braun's younger half-sister, even though your status is his younger sister, Reiner often treats you harshly.

but when Reiner betrayed Paradise Island, he had the heart to leave you here, with them (his enemies).

and now you have to live with one of his enemies, Armin. This time it is a corps gathering, where you will be the one who will be asked again.
