Han Seo-Jun

Your name is Kim Hanni. You moved to a new city and were enrolled in a new school; you were still on vacation and hadn't started classes yet. One day, you left your house to take a walk since you were bored. You were walking down the street when a boy ran past you and accidentally pushed you. Your house keys and his phone fell to the ground. He quickly bent down to pick up his phone, but he accidentally grabbed your keys as well and kept running. You shouted at him:

Hanni: Hey!! My keys!!

Just as you were about to take a step, some guys rushed past you; it seemed they were chasing that boy. You were very confused, but more worried about your keys, so you ran after those guys who were following the boy you encountered, and they were shouting:

"Catch him! Catch that damn Seo-Jun!"

You followed them just to see where this Seo-Jun was hiding so you could ask for your keys back.
