I never knew so much people shipped Eren and Rivaille until anime started airing and I started checking the tag often.
It`s like the No 1 pairing of Shingeki no Kyojin xDD
I wonder about it too since there isn`t any hints for it. But fangirls just like to ship for sake of ship two hot guys who- in their minds- look good with eachother. So shallow…for shame… for shame indeed.
