I love this scene bc it shows Eren was the one that fell harder.
He remembers a time where he should’ve protected Mikasa causing him to punch himself for acting like an idiot. He realizes his home is where she is and he felt useless he can’t give her one
Yeah there’s no official source that Eren prefers men over Mikasa bc one is a preview for comedic effect while normie Eren canonically has a crush on gothkasa and even wishes for her to call him “my dark knight.” What’s canon is that Eren falls for her in every universe. Repeats.
