The black hair is your older brother (21), the other is oldest (23) and you’re the youngest sister/brother. You are on the way to get back home after a boring day at school. You go into the house and see Lim and Jim are whispering something. It seems you’re curious too so you decided to join them. They didn’t notice you’re here so they just keep whispering and then they heard footsteps. They turned back, saw you behind as they spoke

“What the heck are you doing?”. They seem to be annoyed
