Most people assume it's Paulina, since they've seen him making heart eyes at her when he thinks no one is looking (unfortunately for Danny, he's not subtle)
In actuality, it's Sam. But he can't admit that, since it might blow his cover even more. So he just dodges the questions.
One day though he gets swamped by students demanding to know who the lucky teen is. Danny, already drained from the tough ghost fight and not thinking clearly hears Dash yell from the crowd.
"OH hey Phantom! Is it me?!"
Kwan, his ever present shadow, eggs him on, yelling "I heard someone say it's Fenturd!"
"What?! No way it's Fenturd. I'm his number one fan! It's gotta be me"
Danny, almost on instinct, mutters "it's not Fenturd." Before screaming at the the top of his lungs "it's FENTON!"
Immediately the crowd goes silent, and Danny realizes what he's just done. He tries to backpeddle out of his blunder but it's too late. The teens have latched onto his answer and a murmur spreads among the crowd.
Danny, not knowing what else to do, goes invisible and flies away.
It's the next day and Danny's dreading going to school. He knows he's gonna get beat up and harassed three times as much by his jealous classmates.
But walking into school with his friends, he's surprised to find no one is treating him differently. If anything they're being nicer? Flabbergasted, he asks what's going on.
Tucker, never passing up a chance to put his tech skills to use, whips out his PDA.
"Le me just hack into their messaging apps real quick... Oh wow!"
"What is it?" But Tucker doesn't answer, and just continuing scrolling and chuckling.
Danny, freaking out and sure it's bad news, grabs Tucker and shakes him demanding an answer.
"Okay, okay! Chill, it's fine! First of all, you know that Sonic meme? Woah, he's bisexual? Well, just about every person sent that."
Sam snorts at that and danny turns to glare at her before prompting Tucker to continue.
"Secondly, they're taking it as a real star crossed lovers thing. You know, ghost boy falls in love with the son of ghost hunters? There's even speculation that that's why you dissappear when ghosts attack. To meet up with your boyfriend after.
Looks like they've actually all agreed to keep this quiet, so that they don't expose the two lovebirds. Who knew this school was full of romantics?"
Sam just smirks and pats Danny on the back. "Wow Danny, I think you might be the first person in history to be both Romeo and Juliet. Congratulations!"
Danny just puts his head in his hands and groans.
"Uuugh, what even is my life..."
