I'm not sure which Kyungsoo's MBTI is the real one.

I looked up MBTI because I was curious, and while some say INTJ, others think I might be an ISFJ; it's really confusing. I still don't know which one is right. I think they are definitely a J since they are meticulous, but they also have some T-like sides, and at times seem like an F, so this part is a bit confusing. Which one do you all think is correct?
