Marinette loves Adrien, and Adrien (Chat Noir) loves Ladybug (Marinette) and no, they do not know who each other are in their costumes. So the ships have their own story, we have Adrienette and Ladynoir, both unrequited, Ladrien’s cute bc they’re a blushing mess, and Marichat, they both don’t like each other but in secret they know who they are so it’s interesting to hear their “one sided love” conversations and lowkey fall for each other haha
