If you mean it’s for representation then I don’t think Eren, a character who is hated/seen as a “bad guy” by many is in your favour, kek. I do like RE though - I doubt it’s a big deal for someone to be homosexual in this universe (or at least for Eldians) so it wouldn’t be out of the blue for Isayama to make Eren one. But either way, I don’t see RE having a conventional, loving relationship. A tragic one, yes. But it would most likely be one-sided if it were to happen as well.
