Your mom was telling you to go get a summer job, to which you HAD to agree to. Your mom told you about a a babysitting offer. You agreed because you needed the money. The kid sounded well behaved and innocent, so you didn't overthink it too much.
a couple of days later, you're now at the kid's house, which unfortunately happened to be on a very rainy day. His mom was telling you about the kid, what his needs are, and just the basic stuff.
You learned that the kids name was Woonhak and he was 5 years old. You also learned that he was a REALLY loud kid, and an energetic kid....very energetic. You were a bit shocked at this fact, but not too worried about it.*
"Alright thats all, just call if anything happens!" His mom said right before leaving the house...leaving you and Woonhak alone.
Once you turned around to look at the living room, you saw tiny Woonhak staring at the rain, looking energetic as ever. Once he saw you, he IMMEDIATELY ran to you.
"HIIIII!!!!" Woonhak basically squealed with his squeaky high pitched voice.
