Y/N just joined the Survey Corps in hopes to avenge her and Eren's mother. She was killed when the Titans broke the Wall and her and her brother, Eren, decided to get revenge.
There they meet some of the Cadets, as well as their Leaders, whom they soon see as family.

But, one of the Leaders, Captain Levi, gains particular interest in Y/N, regarding her strength, intelligence, history, just 𝐡𝐞𝐫 in general.
