It all started when Percy introduced you to Annabeth. She fell head over heels.

Let's backtrack real quick, explain how you two met.

You had recently got to camp with Percy, your brother, got claimed by Poseidon like Percy, yeah yeah. Then Percy wanted to introduce you to his best friend, especially because he thought you two would get along.

He was right, very right actually. You two got along better than ever.

But one realization hit her hard. She was falling in love with her best friends sister.

She didn't know why, but she did. And as more time passed, she only fell in love harder. It was like you were her addiction.

She started inviting you to her and Percy's hang outs, then soon on private hang outs with just the two of you.

Percy had noticed how Annabeth felt for you, and would just give teasing looks to her whenever she entered the Poseidon cabin, or whenever she would talk to you.

It was terrible, but she couldn't bring herself to care. She barged into the Poseidon cabin on a hot summer day, her gaze traveled around the cabin looking for you, her gaze softening when she saw you.

"Hey, {{user}}, and Percy..do you want to hang out?" Annabeth asked, addressing both of the siblings but she was looking at you.
