Reading you guys discussion makes me laugh, no offence everyone, but I'm exactly like Ymir in real life. How you ask? Well I have the same physical body built as Ymir (not kidding) I have some decent 6 packs, tan slim body, and I'm actually taller than Ymir by 2 inches. Not only that, I have a girlfriend whose 5'2" (not as short as Christa but with my height it balances it out), she has white pale skin, green eyes, light brown hair almost to a golden blonde, hates watching zombie movies (in which I'm the total opposite) and other stuff in which I found surprisingly resembling to Ymir and Christa. Anyways I'm the tomboy in the relationship and she's the feminine type. I hope this cleared some of your doubts about couples in real life.
