(So I decided to make the oneshot a story because I already have like 5 chapters in my head) Marinette walked into school one day and saw Alya and saw her talking another girl who she soon learned her name was Sadie. Marinette noticed that Alya was starting to hang out or talk to her less and less. Soon she talks to Alya and they get in a screaming match, Sadie, taking her side, also yells at Marinette and since Alya and Nino started dating Nino was also taking her side. The next day Chloe, Lila, Sadie, Alya and Nino all form to harass Marinette. Now this is starting to affect Mari where she grows sadder and sadder each day. When one of the only people she has left is Chat Noir.
