On his first day of school, Adrien is excited to finally meet Marinette, who Chloe had been trying to convince him was a terrible person for years. All those stories had the opposite effect. When he’s almost late for class, most people are already in the room, including Chloe and Marinette. (Slight AU where Adrien is crushing on Mari and doesn’t get blamed for the gum.)
Over the years, Chloe had told Adrien tons of stories about going to school and her classmates. One person that had popped up over and over had been Marinette Dupain-Cheng. Her name was always said with a sneer by Chloe but the stories told about her only seemed like good qualities. As hard as Chloe tried to paint Marinette in a negative light, she never could.
