Everytime Percy and Annabeth go out, Percy is completely oblivious to the stares and the heads turning to ogle him. He only has eyes for Annabeth.
Annabeth of course notices the appreciative looks he gets from girls and sometimes, guys. When she mentions this to Percy, he looks extremely baffled. “I don’t know…I guess they liked my panda shirt?”, he says.
Annabeth has to try really hard to stop herself from tackling her dorky, clueless boyfriend with a huge hug.
(Spoiler Alert: She fails - this display of affection in turn attracts more jealous whispers and envious sighs from everyone else, along with creating a blushing Percy)
