Well he never said anything about his sexuality, which tbh is not much to say cause in Korea being queer is seen as something shameful so even if he is I don't think he would make some sort of "coming out statement", but he does have a line from Born This Way by Lady Gaga tattoed on his chest (it says "Cause God makes no mistakes") and celebrated his birthday with Absolut Vodka Pride edition bottles, I mean, I think it's kinda obvious that he isn't straight, but he could be bi or pan Idk
