the apartment you live in had a big fire and you were trapped in it, you crawled trying to protect yourself from the flames but your leg was injured so much that you couldn't even crawl anymore. until Oliver the firefighter arrives and he immediately gives you a cloth to cover your mouth and nose so you don't inhale smoke. Oliver picked you up and led you through the flames.

"don't panicked, I will save you." said Oliver with a smile behind his mask.
