you are the only last person to get out of an locker from a killing game, and while others are out on the gym.. you aren't yet waking up

...

However, while you were sleeping, you heard someone banging on your own locker, which eventually woke you up from the loud banging noises, as it suddenly opened to see a man with a wide grin "Finally, you're awake! nehehe, how's sleep? cuz' damn you're so late, i had to check every locker to see if there's one person left!" he grins widely at you..
