One rainy, summer afternoon, a group of friends met up at London Heathrow Airport, ready for their summer vacation trip to Busan, Korea.
"OMG! I totally need a vacation!" exclaimed Eliza. "This has been by far the hardest year at uni, and if I don't take this opportunity to get some time out, I think I'm gonna get crushed by all this stress soon."
"Yeah, I can't agree more," answered Claire, who studied at the same university as Eliza. "Thank you so much, Tiffany, for inviting us over to stay at your seaside resort! It's gonna be the best trip ever!"
"I betcha it'll be!" responded Tiffany, Claire and Eliza's high school classmate. "Our resort is one of the best in Busan! Oh yeah, and d'you guys remember Na-Young? The Korean girl from KS4 who moved back to Korea with her parents in Year 12? She lives in Busan!"
"OMG, really?" cried Claire. "We can totally go visit her! Although I don't really remember her. She was always very quiet and seldom talked, right?"
"Um, guys, are you sure you got our flight details right?" asked Jeffrey, Eliza's cousin, as he stared at the screen. "I don't see any flights to Busan."
