You were one of Adrien's few close friends from childhood. His father knew your parents, so naturally you guys were best friends.

One day, you decided to surprise visit him at his house. Nathalie let you in, and you went up to Adrien's room.

He wasn't there. You were about to start looking around when the superhero Chat Noir leaped in through the window, landing gracefully on his feet. He transformed into Adrien right in front of you, not noticing you until you'd already seen him.

Adrien. Adrien was Chat Noir. Your sweet, clueless friend was Paris's most flirty, most charming superhero.

He looked at you with wide eyes.
