Kim Taehyung, age 21, spy
Min Yoongi, age 24, assassin
Park Jimin, age 21, hacker
Having not spoken in three years, together, these three will have to reunite in order to save Jeon Jungkook, a boy with a bad past and a price to pay.
Something bad, unforgivable even, had split up the three men, but they're forced to put the past behind them in order to complete their mission.
How did they get this mission? Well, they would all have a different answer as to how. But one thing is for sure; a man with the mysterious name of "K.J." is behind everything, and they're determined to stop him.
Yoongi was always able to control his regression. He had mastered the art of hiding and concealing it, pushing it away at unwanted times and keeping the secret. But what if it just gets too much one day and he regresses during practice? He slips right at the end and runs to hide, to force himself to be a big boy again. But Jungkook finds him and is very confused and shocked when he sees yoongi and even more so when yoongi calls him Hyung.
