Taehyung enter the car and settles between Yoongi and Hoseok at the very back of the car. Jimin and Seokjin with Jungkook in between are at the middle while Namjoon sits beside their manager, Sejin who is driving.

He tries to control his face when Jungkook suddenly turns his head around. But then when their gazes meet, Jungkook faces the front back.

Yeah he admits that he feels a little bit offended by Jungkook's action but he tries not to let it bothers him too much.

But he does hear what Jungkook told Jimin, "Jimin hyung, can you massage my shoulder for a second." 

Which Jimin agreed.

So, that was why Jungkook turns around. To ask the person behind him to massage his shoulder. But he decided not to when he realized that it was Taehyung behind him.
