Dear Grover,
I'm sorry that you only stuck with me out of pity. I'm sorry I caused you so much pain. I often wonder how much better your life would have been without me. All I know is that I ruined it the second I walked into it. I was given the choice, do I drive the car off the cliff with you in the passenger seat, or do I stop the car and allow you to get out? I think we both know which one I chose. I'm sorry.

I love you.

-Perce xx

Dear Annabeth,
I'm sorry they made you deal with me. I'm sorry I ruined the little system you had, it caused you so much frustration. I often wonder how much better your life would have been without me. I was given the choice, do I let you drown with me, or do I push you to the surface first? I think we both know which one I chose. I'm sorry.

I love you.

-Seaweed Brain xx

Dear Luke,
I'm sorry that you felt like you had to save me. I'm sorry I sent you on the wrong path. You had everything going for you and I ruined it all. I was given the choice, did I let my life go down the drain, or did I save it, ruining somebody else's in the process? I think we both know which one I choce. I'm sorry.

I love you.

-The Boy Who Destroyed Your Life xx

Dear Bianca,
I'm sorry that you're never going to be able to read this. I'm sorry that you're never going to be able to read anything ever again. I'm sorry I ruined you're life. I'm sorry that I took it away from you. If I hadn't been there that day, this wouldn't have happened to you. I was given the choice, did I let myself drown in sadness, or did I give myself that little bit of happiness and cause the death of someone so undeserving. I think we both know which one I chose. I'm sorry.

I love you

-The Cause of Your Death xx

Dear Nico,
I'm sorry I forced my way into your life. I'm sorry that I broke you, inside and out. I'm sorry that I cause you to feel so alone. For you to be alone. I'm sorry for what happened that day. It was all my fault. I was given a choice, did I let myself drown in my misery, or did I give myself that little bit of self-worth but ruin someone else's in return. I think we both know which one I chose. I'm sorry.

I love you.

-The Cause of All Your Pain xx

Dear Rachel,
I'm sorry that I let that chance meeting take place. I'm sorry I let one day, any normal day, define your future. I changed you're fate, for the worse. I was given a choice, get through another day feeling broken, or make that one day better for me but a thousand times worse for someone else. I think we both know which one I chose. I'm sorry.

I love you.

-That One Weird Kid at the Hoover Dam xx

Dear Zoë,
I'm sorry I made the short time we shared together so hard for you. I'm sorry I caused so much trouble and that you had to put up with me. I'm sorry I broke down your walls, only to not catch you when you fell. I was the definition of 'bad, stay away', but you didn't know that did you? I used your weaknesses against you. Weaknesses you only told me because you thought I was different. I was given a choice, live my awful life as it was, or make a short time of my life better but crush someone else's entire world in the process. I think we both know which one I chose. I'm sorry.

I love you.

I LOVE YOU.

DEAR ETHAN,
I'M SORRY YOU SUFFERED SO EARLY IN LIFE. I'M SORRY I WALKED INTO YOUR LIFE DESPITE YOUR COMPLAINTS.

-THE WEIRD KID YOU WISH YOU NEVER MET XX

Dear Chiron,
I'm sorry you had to even meet me, let alone spend so much time with me. I would sometimes wonder what would happen if you had stayed as Mr Brunner, never having to deal with me again and letting me move on to the next poor souls. I was given a choice, let the poor teacher just do his job, or barge right into his life, make myself at home and make sure it sucks as much as my own. I think we both know which one I chose. I'm sorry.

I love you.

-Your Least Favourite Student xx

I love you.

I'm sorry for ruining your life before I was even brought into this world. I'm sorry for all the trouble you went through because of me. I'm sorry that you had to put up with me for my entire life, no matter how short it will be. I was given a choice, leave this world before I truly became a part of it, or break my very first heart, mind, body and soul. I think we both know which one I chose. I'm sorry.

I love you.

-The Worst Son You Could Ask For xx

Dear Gabe,
I'm sorry that I was such a pain to you. I'm sorry that I forced you to hurt me. I'm sorry that you'll probably never read this. I was given a choice, stay the happy innocent child I was, or cause someone to extend my track record. I think we both know which one I chose. I'm sorry.

-The Centre Of All Your troubles xx

This was originally going to just be Percy's letters to his past lovers but it ended up being his letters to everyone he has ever met. ...I honestly don't know how it happened. I left the letters quite vague to let people imagine what they want. The gods weren't mentioned so it could be an au.
