Your friend had been akumatized. You luckily ran away in time, hiding behind a pillar.

Luckily, the two heroes Ladybug and Chat Noir came to de-akumatize her.

While they were fighting, you were hiding, but your akumatized friend had saw you and almost killed you, when you felt someone grab you and move you out of her grip.

It was Chat Noir.

He looked at you, and smiled,

"Hey, you're okay now. How are you feeling?" He asked.
