Fears Revealed

Cat Noir finds out that Ladybug told Rena her secret identity, and after having felt left out and kept in the dark for so long, it's the final blow that sends an avalanche of frustration into motion.
But as he confronts Ladybug, he finds that he's not the only one who has been hiding his deepest hurts, and the two are caught in an argument that will either grow them closer together, or tear them apart.

(This is mostly based on a daydream I made in my head and is probably not how the actual argument will go, but it's a fun read and I really enjoyed writing it. Hope this brightens your day!)
