The kisses

Things are going horribly wrong in Paris.

Adrien kissed Marinette and Kagami in one day.

Timelines are collapsing.

Four kids enter through four mysterious portals. Emma Agreste (Adrienette), Jonas Agreste (Adrien + Lila), Kleo Agreste (Adrien + Chloe), Lee Agreste (Kagami + Adrien).

And there is a battle for who gets to live and who gets to die.
