For me, both Gyeongsu and Isak. I think I’m pretty sure Cheongsang will come back so I don’t even have to mention him
I loved the fried group between onjo, cheongsang, gyeongsu, and isak. I’m so sad the other two had to go and I hope they somehow make a comeback
Also I know a lot of people dislike Na-yeon but I hope she comes back as well. She was in the middle of great character development before she died
One person I DONT want back is gwinam the little shit
