Prowler - [Riren/Ereri]
Summary: Eren Yeager has no family, no house and no consistent friends. He always travels from one place or another, his only real property is an old RV van, his 'home sweet home'.
He was just at the wrong place and the wrong time when his van broke down in the middle of the road. Eren finds himself stranded there until morning when help should come. But just as he was about to sleep and turn off the headlights, he sees a glimpse of a body ahead of the road. Only to find that it was an injured dog. Eren couldn't just leave it alone to die, but he just had no idea what he was getting into.
