"Students, settle down. We have a new student today."

                      'Hello everyone, i'm Nam Woohyun and i'm 7 years old."

"Woohyun, you can go sit beside Miss Park Chorong over there."

                                         "Hello, i'm Woohyun."

"I'm Chorong. Since you're older than me, can I call you Oppa?"

                                            "Of course you can."
