I'm rooting for the friend!!!

I really don't want it to be a BJ alex thing if u know what I mean...in one of the extra episodes in chinwoo and MDs story, that random guy who was a rejected sub for MD. Like MD teased him but turned on him in the end because he really only had eyes for chanwoo. Not that this friend turns out to be the clingy type, but....Dr. beak better not be mean to this kid!!
