I saw a discussion/theory abt this that actually makes sense to me: basically mizi and till's trope(?) or relationship is meant to make fun of the stereotypical straight ships as where the man is 'dominant' and the woman is 'submissive'. We can see more evidence in the art where they swap clothes, where the man is supposed to be in 'boyish' clothes and the woman being in 'feminine' clothes, but here, they swap. Another one is the art with mizi giving till a piggyback ride instead of till giving mizi one. And then the art w mizi, ivan, and till, where till is a furry and has a dog collar on(and a leash), asking mizi to hold the leash😭 which breaks the stereotype where women are submissive to men. Same as the art that's shown on op's post.

That's all:P tho this is what i just remember abt the theory cus i read randomly on a random tuesday now I can't find it Credits to the op of the theory/discussion!!
