Adrien and Marinette have been friends since the first day of kindergarten.
They made a promise, and they don't plan on breaking that promise.
But Gabriel, Adrien's dad, hides Adrien from the world after his mother dies.
They've changed over the years, and become Ladybug and Chat Noir. Saving Paris from the evil hawk moth.
(they don't know who each other's secret identities...yet.)
It's their final year, then high school is over for the two. Gabriel agrees that Adrien can go to school. But he has to listen to his dad and his rules.
Adrien is super excited for this. He's been waiting years to see his best friend, his love. The wonderful bluenette, who he can't keep out of his head.
But when he comes back, Marinette forgot the promise and their friendship.
But Adrien's not giving up yet, he'll do anything to get his lady's love.
