Percy and Annabeth had been dating for about a year. You joined the camp about 6 months ago, and Percy immediately became friends with you... but it turned into something more, you fell in love with each other.

You became his secret girlfriend. Annabeth, of course, doesn't suspect anything, although she is angry at Percy for spending so much time with his 'friend' (you).

Now you and Percy are in his cabin, he is sitting on the bed and you are next to him, making a wreath from the flowers you collected earlier
