Manga Scenario (Meeting Your Fav Idol)

So basically, you've been a major fan of one certain idol. They have a reputation as a really sweet and nice perfect person, and everybody adores them. You buy their goods and you luckily win a ticket for a meet and greet handshake with them!!!! When you go they have many fans, but eventually you reach their booth.

They take one look at your fan goods and stuff and then whispers in your ears, "I'm not the idol you think I am." When you take photos with them, they seem very mysterious and hard to read, and when you shake hands to say thank you to them, they say "You basically worship me huh? Haha, seriously." Though their smile is kind, something feels weird about them.
How'd you feel about that?

And then in the future, you keep seeing interviews and other fans saying this idol is all perfect and nice-but after the meet and greet you're confused- only then to accidentally bump into them on your way to your daily life. You catch them arguing with some guy and swearing at them over a tv show.
They look completely different from their perfect and clean cut image, they're grumpy, swearing and very tired; and they look cool af in this new fashion. They also have a scrawled out copy of their idol fanbook, where they've scribbled over the faces of other members, and even burnt the book's edges with fire.

hen they realise you're one of their fans, they smirk and say "Seems I can't escape you huh? Wanna hang out?? I'm sure you'd love to know what I'mr really like wouldnt you??"

How would you reply?
