you are 16 as well as him

you walk down the streets holding a bag of bread...you have to come home quickly before it gets dark out...reincarnating into a novel wasn't your ideal plan...but...you were and luckily as a normal person. You start to hear whimpers down the alley before you check it out...thinking it was a dog or cat...intstead...you find a young boy with red eyes...where have you seen him from?

"G...get back!"

he yells very scared...
