I haven't read the manga yet BUT ANYWAYS it had the letter she wrote to Historia in english which had me sobbing but then I go to the comments and men were saying they weren't in love? O.o HUH!? I thought through the entire show that they always liked/loved each other..? Even if Historia never out right said it or showed immense affection she's never been that type of character? But she was closest to Ymir and seemingly loved her in her own way so seeing those comments really confused me? And their only reasoning for her not having been in love with Ymir is that she got pregnant?? Okay? Isn't she canonly bisexual? And wouldn't she need an offspring being the queen anyways? But what really got my blood boiling was the straight white men in the comments saying YMIR DIDN'T LOVE HER!?! AND THAT SHE NEVER SHOWED AFFECTION TOWARDS HISTORIA AT ALL!? Idk how they watched the anime or read the manga seeing as how they must be both blind and deaf
