Such a beautifull friendship (Jean x oc)

the tragedy

A few hours later we all woke up and got ready for training, and yes even though we had finished the 3 years we still had to train. Today it was hand-to-hand training in groups of two, so I decided to get together with Jean, the instructor explained the rules and we were able to start training. Jean was strong, even if he's not always smart enough to use his strength intelligently, he was still strong, but against me I always felt like he was holding his strength back, I had always been able to hold him in hand-to-hand combat, but today he seemed distracted.
Reiya : Hey horse face, don't hold back your blows, I'm not made of sugar!
Jean : All right ma'am, as you wish.
So he started to fight seriously and I was beginning to have trouble countering his blows, but Jean as he was, let himself be distracted by a new me and I took advantage of the moment to put him down. I found myself standing over Jean, holding both of his hands on the ground and looking him in the eyes.
Reiya : Haha, you shouldn't have let yourself get distracted. I laughed and teased him.
Releasing my grip to get up, without having time to understand what was happening to me, I found myself on the ground Jean bent over me, he moved his head to my ear.
Jean : You shouldn't play with me like that Reiya. Then he got up and left as if nothing had happened. Armin and Marco came a few seconds later to see if I was okay because he saw me on the floor.
Armin: Are you okay? Are you all right?
Reiya : No, don't worry, I'm fine.
Marco : I'm going to go and yell at Jean, he went too hard this time !
Then he goes to join Jean. As the training was in the morning, in the afternoon we were called to reinforce the walls, we were all laughing and relaxing when suddenly, turning our heads we saw the colossal titan with our equipment we clung to him and tried to kill him but in vain, he had disappeared, we were all upset but Eren seemed even more downcast, but suddenly I made a remark to them.
Reiya : I don't want to worry you but there is a hole in the wall and titans are coming in !
They all seemed scared but in my opinion, they remembered that we had entered the survey cops because we were ready to die and then we went on the attack. Marco, Jean and I, had gone to one side, showing perfect cooperation, we ablated the titans one after the other by cutting their necks. Once the city had been evacuated, we had gone to take refuge in a house with the others when suddenly we heard a huge scream, then we saw a titan fighting against the others, a deviant surely. After a while, we were back but some of our comrades were missing. After letting us rest we were asked, as was the garrison, to clean the streets of the district of all the rubbish they had left behind. Praying not to run into any of our missing comrades, Jean, Armin and I were walking down the street when suddenly the most horrible thing we could have hoped for happened ; Marco was leaning against the wall of a house, half of his body was missing, I couldn't believe what I was seeing. As a reflex, my body rejected my entire meal and I began to burst into tears. Jean didn't say a word, so Armin took us by the hand and brought us back. Armin accompanied Jean to his room and I to mine and then left to tell the others the news. I was devastated, our friend, comrade with whom we had spent the last 3 years had just died. I was sad, but I took my courage and went to Jean's room, he was sitting on his bed, staring at Marco's bed with eyes full of tears. I sat on the floor in front of him and took him in my arms he also put his arms around me, I hugged him hard and felt that he was starting to cry, which made me start crying again. After what seemed like several hours of hugging, I decided to lay him down on his bed and go back to my room, however, he took my wrist and asked me to stay close to him, so I slipped into bed with him and took him in my arms to fall asleep.
