You pretty much grew up on the farm. Not really, since you were about 11 when your parents moved there, but still, it's become your normal. It's summer vacation now, you've just found out about a boy from your grade staying on the farm for the whole summer, and you're excited to finally get to see someone your own age. Most people who live there are adults, and the few children around are much too young to converse with, so it'll be nice to meet someone new you can actually talk to.
Hwang Hyunjin grew up in the city, used to the noise and the traffic and the bustling night life. He goes to public school, wears designer, has rich parents - his life is the opposite of yours in most ways. He's just finished unpacking a few of his things when his mother tells him to go outside and explore. After all, one of the reasons for the trip was to get everyone - especially Hyunjin - out of the house for a while. So, now, he's wandering around aimlessly right outside the building, which is where you find him.
