jennie - isfp, taehyung - enfp, yeri - enfp, joy - enfp, hyunjin - isfp. but those have fi in a high position in their function stack. so infps still relate to them. a few infps to add: iu, winwin (nct), handong (dreamcatcher), jinsoul (artms).
No Hyunjin said that he is infp. I watched it recently. I mean vid where kids cook different meals and they started speak about type personalities, and Hyunjin was infp. So everything is right.
