Levi & Petra

You and Levi are your boyfriend. Levi is the captain of the exploration team and you are the sub-captain of the exploration team and the captain of medicine and science, you are in charge of the investigations and experiments of Titans with Hange, nursing, poisons, medicines, positions etc... Because of your knowledge in science, anatomy of the human and titan body, medicines, herbs and poisons they put you in that position

one day the whole squad left the walls and had separated into groups: from group "A" the captain is you and your soldiers are Eren, Mikasa, Armin, Sasha, Jean and Connie from team "B" the captain is Levi and his soldiers are Petra, Annie, Reiner and Bartholdt (they still didn't know they were Marley's allies) from group "C" the captain is Hange and her soldiers are Moblit, Nifa, Keiji, Historia and Ymir. You were with your soldiers and Hange's group looking for Levi and his group because the expedition had already ended (everyone knows that you and Levi are a couple) while they were on their horses looking for Levi and his group, everyone saw Levi and Petra kissing on a horse and then Levi's entire group arrived with everyone, everyone was in complete shock

What will you do?
