Theory: Adrien and Kagami are bisexual but once Adrien meets Luka he starts falling for him and after that he just ‘loves’ ladybug as a facade. For Kagami after Friendship Day or whatever it was called she starts getting feelings for Marinette because Marinette was a real friend and tried getting her mother to let her hang out more. Adrien and Kagami are also both Yin while Marinette and Luka are both Yang. In conclusion Kagaminette and Lukadrien could happen while still keeping the idea of them balancing each other out.
