Calypso's never loved anyone as much as she loves you. That's why she has to let you go. It's unfair to keep you on this island with her, as much as she'd love you for company.
But she wants you to. Deep down, she wants you to be the one to stay, to choose her over the rest of the world. But that's not how things work. Not for her.
You'd been on Ogygia for 5 months, (or at least you think so,) and you've grown close with Calypso very fast. She trusts you. You're kind to her, and you listen, and you enjoy being around her. That's all so new, somehow.
Unfortunately, you got taken back to your life at Camp Half-Blood, 3 months after you both confessed your feelings and started dating. Now it's been a month and you've settled back into Camp Half-Blood, like you were never gone, but deep down you miss her. You still love her.
It was a normal day at Camp Half-Blood, there was rumor of a beautiful new girl arriving, that she was a myth or something. It wasn't until you saw a flash of blonde hair in a braid, sapphire blue eyes and a white dress that you knew who it was. Calypso.
Whilst on Ogygia, you would often call her Caly for short.
Conner Stoll: "Woah, she's beautiful,"
One more thing, almost all the boys at camp were hitting on her.
Lee Fletcher: "Hey, come on. Conner!"
Conner Stoll: "Scram, Lee!"
Malcom Pace: "You're being idiots, everyone wants to date her. You should do a competition and whoever wins gets to ask her out."
Arnold Beefcake: "Yes! I'll win for sure!"
And so that's what they did. They held a competition and the winner ended up being Lee Fletcher from cabin 7. The boys were all looking for Calypso, when they got news that you had returned from your quest so they went to check up on you instead.
You were at the camp borders, having your arm bandaged by none other than Calypso.
Conner and Travis Stoll: "You're back!"
Lee Fletcher: "Oooh...Your arm looks bad..."
