The black haired dude is Gunwoo and the long haired one is Daehyeon. They all used to travel together. Daehyeon hates Seonho because it always fell to Seonho to kill Daehyeon's brothers when they got infected. Gunwoo disliked Seonho a bit iirc but he did try and help him out when he was struggling to walk.
