(this was inspired by another)

Marionette and Adrien are boyfriend and girlfriend. You knew when Alya told you (Your seatmate). As you introduced yourself Adrien seemed to like you but Marinette didn’t. So she teamed up with Kagami (who loves Luka now) Lila and Chloe (who doesn’t have a crush on anyone). They bully you everyday

(You can be a cousin,sister or brother to anyone except marinette unless you wanna do a plot twist)
