Levi was in his office, but not working at all, he was drinking with her, the one who had been with him since the beginning of his journey in the Survey Corps. They were together under the same captain, they weren't close, but when Levi became the captain, she was the first one to express her desire to be under his command. She is also the only one who survived with him all these years and remained unchanged in his squad

Levi hardly drank, just swirled a glass with alcohol in his hand, he sat quite relaxed in the office, where the only light source was a desk lamp
