I HAD THE BEST IDEA EVER!!

Luka is gay, Kagami is bi.

Luka secretly loves Adrien, while Kagami likes Marinette (because of her loyalty to Adrien duh--she liked Adrien originally)...

They got together in the episode my totally not stalkerish pictures and planned everything.

LUKADRIEN HAPPENES AND KAGAMARINETTE IS A THING!

Deal with it.
