"'Gainst death and all-oblivious enmity

Between Sana and me, Jungkook began leading a kind of double life that he was never able to resolve. He divided his time between the freeness with us and a straight life in his "successful" group. With the latter, he dramatized his own conflict between his wringing nostalgia for us and the irresistible attractiveness of fame and "glory". There was no easy resolution of their differences, which reflected the clash of values within himself.
Contrary to his expectations, Jungkook did not find himself "redeemed" after his group had made it big in America. Something else was happening in Jungkook's life at this time, and that something was Nayeon. But that something tired him so, so he turned to one that did not-- and that ONE was Sana. Unlike Nayeon, he was not overwhelmed with Sana, because she didn't make him feel emptiness or even falseness when she left him for the day.
With us, he saw no value of inventing a sympathetic character who fled his past to embrace what he imagined was the freedom of his future-- he just wanted to be with us. So Sana naturally became the morally consistent presence for the both of us, a solid backdrop, an intermediary between the dazzlingly unpredictable whirlwind that was us and the humdrum corporate politics of the world around us.
