Jackson and BamBam have been best friends ever since they were young. Both of them had an interest in rapping, so that was their favorite thing to do together. Years passed, and although they were both great rappers, only Jackson gets opportunities because of his older age. As BamBam struggles through high school, he feels forgotten and sad while he quietly cheers on his hyung from the sidelines. Good talent goes to waste, and it seems like Jackson has no time for the schoolboy anymore.
