I am a huge Jeyna shipper, so here's a little clip from Reyna's POV.
-the hiddenn lover
When he left, a part of me died. I missed the feel of his soft skin electrifying my own, even with a light touch. I missed the way his sparkling blue eyes would bore into mine. I missed how good of a friend he was to me. I miss the way he used to be mine. I miss the way we were so close to that little thing called love. I missed the old son of Jupiter, especially while watching this son of Zeus walk hand in hand with that daughter of Aphrodite. I miss the old Jason, my Jason.
When Perseus came, I knew that something was wrong. He came around at the same time that Jason left. Percy wasn't supposed to come. He wasn't supposed to be my partner in lead. He wasn't supposed to be the one I had to spend hour of every day with. Percy wasn't supposed to be the one to support me; I was too strong for that. Sometimes I slipped, though. It was nice to know that there was someone else in my situation. It gave me hope that I still had a chance with my love.
When I saw that big flying boat come in, it was hard to restrain myself from going insane with anticipation. My heart was about to explode from happiness when I first saw him, but it didn't last long. I was wrong; there wasn't anyone in my situation. He had forgotten me. While Percy spun his love in his arms, I stood there alone. Again, I died. My heart stopped. He hadn't remembered me, he had found someone else.
It just wasn't fair; life wasn't fair. Not for me, it was never fair for me. I would just have to watch him, Jason, slip away from me. I would have to live my life without him.
I hope you enjoyed it!
