I have some of their types down but I'm not very sure about them. Here we go:
Jin LSE-Si... or Gabin, but definitely Delta ST
(there's someone from every quadra, that's their appeal)
Hanbin ESI-Se (or Maxim - Jiwon's supervisor? an aggressor type for sure)
Jinhwan IEI-Fe... or Delta?
Still in need for suggestions for Yunhyeong & Chanwoo.
