Disney Girl Fan owns nothing but her own things.
Adrien was in front of the scene.
He decides to cry for her in sadness.
That's the moment Plagg came out and told him "You should really go save your true love".
"You're right" Adrien replies.
He decides to save her and transform into Cat Noir behind a Bakery shop.
He runs in and holds back Cloe who demands him to let her go "Let me go! Let me kidnap that witch!".
"No! Marinette and your father...run!" Adrien replies.
They both obeys and runs to their car.
But Adrien didn't see her fleeing from the scene and quickly scrambled to the Bakery store, she tranforms into Miraculous Ladybug.
She broke the red barrette at the end shortly after receiving a kiss from Cat Noir in order to thank her for the rescue.
Everything is back to normal and the couple kisses each other once more.
The end.
