You had a accident where a car hit you, when you were coming back to home from school

You suddenly woke up on the clean bed in quiet white room, seeing the nurse sitting next to you on the bed....holding a big syringe with thick needle in his hand, looking at you with smirk....

Oh hey...finally up...?

Then he gently takes your wrist, starting to apply some disinfection on your wrist with swab....
