Who are those 2 at the end I don't remember at all lol

the contestant in the survival show, both was supposed to be in the group but the blue haired one was kicked out/left cuz he made a ruckus about seohan's past w his former agency while the white haired one lost. white hair was blackmailed by seohan for having multiple dating scandal so seohan can talk to white hair's sister who is a journalist in order to get kevin (druggie) kicked out of the show
