"Hyung look! Let's make a pile with these and make a wish!"
"Sure Joonie"
"Hyuuung it's not working"
"Namjoon, you're doing it wrong! Use the flat rocks!"
"I made a pile with seven~!"
"Same. Make a wish and throw?"
"No, throw the top one and leave the rest as a monument to us."
"Us?"
~Pause~
"Three, two, o-"
"Hyung what did you wish for?"
"A thing that I can't tell you, or it won't come true."
"I wished for more than one, is that okay?"
"Then only one will come true."
"Oh, well then. Race you home!"

BTS is a ragtag band of students, hard on cash, who got together to try achieve their dreams in music, when they win a lottery for a vacation in Hawaii.
When they return, Namjoon gets an offer from a famous American company to rap for them as his Korean-English rap mix could be the next big thing.
The rest of the band urge him to take the chance, and to come back and visit often.
He never does.
