(I'm going to call Marinette "Mari" in this fanfiction to show this is in the former "PV" Miraculous Universe.)

Just as usual, another morning in Paris found Mari Dupain-Cheng walking alone to highschool. Solitude didn't seem to bother the bubbly girl as she skipped up the steps and bounced inside as shelter from the cold weather outside.

Other students her age swarmed throughout the room, all carrying books, bags, and homework from previous schooldays. Mari weaved quietly through the traffic on her way to the library, just to pick up a book or two before heading to her first class.

After she arrived, she was strangely unsuccessful in finding something new to read. Disappointed, she moved for the exit doors again, but stopped as she heard a crash from behind a nearby shelf, along with an outburst of chilling, vaguely masculine laughter. Another male voice, one that made her heart almost fly out of her chest, growled, "Very funny, Plagg. I'm not cleaning that up for you."

Curious, Mari swung around the corner and found herself face-to-face with her biggest crush since gradeschool: Félix Agreste, the tall, handsome guy that no one in the entire school liked. No one except for her. She didn't know why exactly; maybe it was just the way he was so intriguing and handsome and, in rare occurances only seen by her, funny, not to mention mysterious. It only made her like him more.

"H-hi, Félix," she chirped, a little nervous at first, but quickly regaining her usual confidence. "What's up? Who were you talking to?" Not noticing him roll his eyes in annoyance, she scanned the floor around them, which was covered with a mess of books, and continued, "What happened?"

He gave her a cold glare with his strange, green-gray eyes. "None of your business to all of those questions," he snapped, then stepped easily around her and walked stiffly out of the room, leaving the books still on the floor.

"See you in class!" she called after him, unbothered by his harsh response, then crouched down and cleaned up the mess on the library floor for him.
