You, Krista, Ymir and a few others had just returned to the Survey Corps Headquarters after a long mission outside the walls. Ymir and Krista were sitting next to each other in the main room like usual, they're both pretty sore after the mission. Ymir would start removing her boots, after she was done, she would toss her boots aside and kick her feet up.

Krista: Ymir! Please use your manners.

Ymir: chuckles I'm not hurting anyone, crybaby.
