After season 2, everything is getting back to normal after the 'Heroes day' battle. While Ladybug and Chat noir are looking for the newest villain, and fighting her monsters, Adrien and Marinette start looking into the history of the miraculous. After a few months of searching and a very special birthday gift, the pieces may all finally click into place. But will it be too late? They are 16/turning 16 in this. There will be Lukanette, Adrigami, maybe some Marcaniel and Julerose. The love square is going to happen, but I think that not having them outright get together would be healthier.
