Q. You are known for being a 4D, has there anything that you have imagined to an extent before ?

Taehyung : I do think about erotic stuffs, but I mostly imagine myself being Iron Man. I have a few ideas planned out on how to make me fly. Maybe launching myself off the plane after sticking on to it, or put some fuel in a jet air and stick myself to it. I could possibly fly if I do this.
