Forced to Love

LEO

I couldn’t understand what had happened.
I came back from my quest, relieved to be home, and now all I wanted to do is leave. Eliza’s breakup with me was so sudden. Emotion of anger, guilt and sadness welled up inside me.
I did what I always did when I was mad, built random stuff. My brain went into autopilot mode as I built a random contraption in bunker 9, hammering loudly and fuming. I contemplated on what happened. Sure, the whole marriage thing was forced, but I saw the way eliza looked at Nico. That sure wasn't forced.
Plus, I saw the ring on her finger. It was hard not to look at it, it was gorgeous. Eliza had to accepted that. I was mad at Nico, for stealing my girl. I was mad at Eliza, for cheating on me why I was away, doing life threatening things! What if I had died! would Eliza and Nico just shrug, say, ‘oh well!’ and get married!?
I was mad at myself, and guilty. In a tiny way, I was relieved. I wasn't sure if it was going to work out for me and Eliza, and I had the tinest, smallest dragon sized crush on Percy’s other sister, Coral. I know, i know. I had a thing for Poseidon girls. what can I say? Coral is the most selfless, fun, kickbutt girl he had ever met. She could wipe out some monsters with some sick skills. I was still really mad.
I stood back to look at what he made. Sure enough, it was a musical instrument. I strummed it, and to my surprise, played a very sad melody. its gears clicked and it repeated the song. I’m no songwriter, but I ended up singing softly along to it with a poem I wrote.

I wish I had more time
was this quest a mistake?
I've loved you but you unloved me
I do not understand.
I do so well with machinery
but your heart I broke.
It seems I can never repair it right, because it has been given to someone else,
I wish I had more time
more tools, no materials
I wish I had had more time.
You left my grasp and slipped away while I was turned
Fell to another while I was away
tears and broken hearts, the things i can never repair.
I do not understand.
Too quick and I cannot fathom
the things that are happening.
I couldn't find comfort, too alive.
I can't fix anything I don't have.
I cannot fix your heart
because
My heart does not work either.
my engine is gone
my toolbelt missing
my heart broken.
I never had enough time.
So impossible but it happened
What is done is done
shut down, thrown away
goodbye my hopeless love.
I never had time.

When I stopped, I realized I had been crying. I put the contraption away and sat down, my face in my hands.
About ten minutes later, I started building again, but this time with purpose. I was building a messenger.

Notes

What is the messenger for? And what is it?
