Mikasa has romantic feelings for Eren but doesn't know it yet.

When she looks at her scarf her heart skips a beat.

Whenever someone mistakes him for her boyfriend(with strangers this is quite often)she starts to blush like crazy.

There is no doubt in my mind that she likes him. And if you think she doesn't you need to go rewatch the anime(I noticed that blush).

Now I just gotta say this.

I'm, like, 85% sure that there's gonna be some romantic moment with Eren and Mikasa. Don't know how it's gonna happen but I know something is going to happen.

Why? Because the scarf Mikasa wears is a reference to the red string of fate in Japanese folklore, the red string of fate represents a connection between soulmates and lovers.

If you don't believe me you can go to trivia in the wiki.
