EreSasha

EreSasha is the het ship between Eren Jaeger and Sasha Braus from the Attack on Titan fandom.

Canon
Sasha and Eren meet on the first day of training. Sasha steals a steamed potato from the kitchen and eats it during initiation. She is questioned by Keith, her head instructor, while he performs the "Rite of Passage" ritual on them. She gives him "half" of the potato (actually a much smaller piece than the one she kept for herself) in a doomed attempt to appease him, and Eren is seen watching the whole thing with a shocked look on his face. Later on, she is ordered to run around the premises for 5 hours as punishment. And Eren watches her from afar in amazement.

These will not be the only times Eren will be amazed by Sasha. Sasha, along with Eren and the others, are assigned to maintain the cannons on top of Wall Rose in Trost District. She steals some meat from the Officer's provisions and offers to share it with them. She enthusiastically predicts that after they reconquer Wall Maria, they will be able to keep cows and sheep. Eren is once again flabbergasted at this and asks Sasha if she wants to be in jail, wanting to protect her since she could be jailed for still highly priced items, such as meat.

Eren admires Sasha once again, moments after the incident with the meat. Suddenly, the Colossus Titan appears out of nowhere and breaks the gate of Trost with its foot. Everyone is knocked off the Wall, but Sasha manages to save Samuel from falling off the Wall. Eren, who is watching it all from a near position in the Wall, looks stunned, as well as relieved by the fact Sasha saved Samuel from what would've been a tragic situation.

After joining the Survey Corps, Eren is assigned to the Special Operations Squad and sent to an abandoned castle which had formerly served as the base of operations for the Survey Corps. While there, he is tasked with Titan experiments on his Titan. And while being there, he is away from the rest of his fellow trainees. Returning some time later to some of his classmates from the 104th Training Corps who have opted to join the Survey Corps, Eren sees Sasha, along with his other friends, and greets them with a smile, happy that they joined the Survey Corps, like he had hoped.

During the Royal Government arc, Sasha is picked by Levi Ackerman, alongside her friends of the 104th Training Corps, as a member of the new Squad Levi, and is stationed with them in a lone house within a forest, where they are hiding in order to protect Eren and Historia from being kidnaped. After she is discovered stealing bread from the few supplies that are already present there, a discussion with her comrades arises, which reminds Eren of his old squad. When Historia and Eren are indeed kidnaped and taken to the Reiss chapel, Sasha takes part in the operation to rescue them. Eren is freed, and manages to control his hardening powers and stops the cave they were on from falling. As the squad retrieves Eren, Sasha approaches him cheerily and exclaims how relieved she is that he was able to be taken out of his hardening form. Then, she falls to her knees and bows down in front of Eren thanking him for saving them all. Despite her relief, and her huge smile, she starts tearing up as she confesses that she was worried Eren was not going to make it. er

Eren, Sasha and their squad travel to Orvud District, where they plan to fight Rod Reiss. As Rod approaches the Wall, the members of Squad Levi prepare themselves for his Titan's arrival, and Mikasa notices that Sasha hasn't been eating so she asks her if she's okay. Sasha replies that she's just not hungry, to which Eren asks in disbelief if there's something wrong with her. Jean informs him of all the stuff that has been happening since he wasn't with them, all of which left them scarred. Eren gets concerned and simply stays silent.

Time passes, and the preparations for the retake of Wall Maria are finished. The day before the operation, the soldiers have a special dinner with meat to celebrate their upcoming mission. Seeing the meat, Sasha goes crazy and tries to eat it all by herself. Connie and Jean try to stop her, and Jean is bitten for his trouble. So eventually, Eren tags along with Connie to restrain her, until Eren realizes that she is more calm. As he and Connie reflect on how much things have changed in the three months since the battle of Trost, Eren has a fond memory of Sasha back when she stole the meat.

Years later, during the Marley arc, Sasha and Eren help their friends assemble a train line. On their road back home, Eren mentions that Zeke only has two years left to live before he dies, so he ponders who should take his Titan when he himself must pass it on. His friends start offering themselves, including Sasha, who says she's the most reliable with combat experience. However, Eren cuts them abruptly and tells them that he doesn't want any of them to inherit his Titan powers because he considers each one of them (Mikasa, Armin, Jean, Connie), including Sasha, important to him, more than anyone. And he tells them that he wants them to live long lives.

In the year 854, Sasha takes part in the Survey Corps' attack on Liberio, planned by Eren. She regroups with the other Survey Corps members aboard the airship, where Eren is also in. Hearing something over the commotion in the ship, Sasha turns to see a girl aiming a rifle at her. Before she can react, the girl shoots Sasha in the chest. Meanwhile, Eren waits in a room with Zeke and Yelena aboard the airship when Jean arrives, saying Sasha was shot. Later, Connie comes in to announce that Sasha has died, and Eren asks him about her last words. Hearing that it was "meat," Eren begins to have flashbacks of Sasha in most of her memorable moments, when she was the happiest, relating to meat. And he remembers, yet again, the time when she stole meat before the battle of Trost. Eren then has a mental breakdown, and begins to laugh desperately. He didn't laugh because it was funny; he laughed because he couldn't take it anymore. The same as when Hannes died. He laughed at himself for feeling so helpless that he couldn't protect the ones he loves the most yet again.
