Taehyung used to be the type of person who smiled a lot and had a very different way of thinking about things. Some people called it 4D; he called it being himself。

Fast forward to years with BTS, his family, and the experiences that affected him like losing his grandma and going through the daily netizen shenanigans, he's grown more comfortable with not smiling and not acting like he's happy when he's not。

because of that comfort in his own skin, though, he's gained some really unhealthy habits. His almost confident air makes it very obvious if he respects someone or not。

Not only that but he's developed an almost misanthropic view of people and gets suspicious of their motivations- though he's refined enough to not say that to their face in their first meeting of course。

Nonetheless he still loves his bandmembers to bits as well as his actor hyungs. And he still smiles to everyone so no one that's not close to him really knows about his own negativity that he also judges himself by until he has a reason to doubt someone for it。

all of this is why he's using his time here to relax from all the stress and recuperate before each time he has to go back to work。
