So I'm really into typology (basically MBTI/ennegream related sciences) and have narrowed down idols of each possible type 
while many take the test on 16personalities, it is inaccurate and actually a Big 5/OCEAN test which measures something totally different. Who do you share a type with? If you do not know your type, here's a good albeit long test you can take
INFP: Yugyeom (Got7)
ENFP: V (BTS)
ISFP: Momo (TWICE)
ESFP: HyunA
INTP: Go Won (LOONA)
ISTP: Hyuk (VIXX)
INFJ: Yves (LOONA) (sorry for repeating LOONA twice, but there are so few INFJs and INTPs in kpop!)
ENFJ: N (VIXX)
INTJ: Sakura (IZ*ONE)
ENTJ: Tiffany Young (not really an idol anymore but ENTJs are kind of rare in kpop as well)
ESFJ: Wendy (Red Velvet)
ISTJ: D.O. (EXO)
ESTJ: Chungha
