Mikasa and Eren have been by each others side from the very moment Eren saved her. From then on we saw Mikasa use her power in order to keep Eren safe and away from harm. She’s even ready to give up her life in order to save him. She truly cares about him, it could also be that she loves him, however from the things we’ve seen It doesn’t seem Eren doesn’t love her back, as family yes but a lover, we still don’t know.

The above image is awesome, it shows both of them in love while Eren in his awesome Titan form. The image was done by Jeraa, who loves the anime to bits. Plus I really like this work of hers, if you do too, be sure to go ahead and check her work out.
