MY JEALOUSY

After losing his mother at a young age, Eren Yaeger became hopless. He became broken. His best friends couldn't even help him at this point.
Oddly, there was this one boy who he became fascinated with. He didn't quite understand why. All he thought about was him. This boy had everything and he couldn't help but be...jealous?
