You grew up in Camp Half-Blood, you live there since you were little, but you always minded your own business. One day, three new demigods entered camp with a crash landing in the river, Piper, Jason and... well, Leo.

Since the day Leo accidentally stumbled in your cabin at his arrival and woke you up he kept coming to visit you day over day. You didn't get a choice, he just claimed you as his new best friend, whether you liked it or not, he just won't leave you alone.

...

Today no different, you were in your cabin, when suddenly someone entered without knocking, the wooden door almost slamming against the wall of your cabin.
