JeArmin

JeArmin is the slash ship between Jean Kirstein and Armin Arlert from the Attack on Titan fandom.

Canon
Ever since their very first expedition outside the walls, Jean and Armin have remained very close friends.

Armin tried to protect Jean after he was knocked unconscious during the Scouts' operation to retrieve Eren.

When Jean was about to be killed by one of Kenny's subordinates, Armin shot her to save his life.

When Armin and Jean were disguised as Historia and Eren, Jean struggled to watch as one of their captors felt up Armin and made him cry. Later when Levi instructed Armin to fix the man's gag, Jean did it for him.

Armin told Jean the real death of his parents, explaining that they were killed by Military Police.

Jean places great faith in Armin and repeatedly turned to him for advice when their situation became dire during the Battle of Shiganshina.

When Bertolt burned Armin, Jean cried at Armin's supposed death and was relieved and emotional at his revival.

Fanon
Armin and Jean at the end of some volumes are together like 21 or they always are near.

Some people think that Jean accepted Marco’s death thankfully for Armin, who seems to take care about him. Armin in one OAV was in team with Jean and he wanted to help him. When he broke his legs he was unhappy because he wanted to be useful for the brown haired one.

The shippers also look at Jean’s cries like a manifestation of love for the blonde guy.

Fandom
A lot of JeanMarco shippers say it’s an insane ship and it make them unhappy. Aruani shippers tell JeArmin shippers that Armin won’t be gay. JeArmin fandom, instead, is very quite and nice. They always say that Marco was a good character but they can’t ship Jean with a dead person. It’s shipped only by manga readers and a few anime viewers by the last episode. Is one of the most shipped yaoi ship in Attack On Titan in USA and England.
