So in the last chapter jungwook and jaewon were fucking and junkwook's step bro(the blonde guy) is watching them from some hidden cam and is pissed so calls the guy who he fucks with( who looks like jungwook but has yellow eyes) and that guy goes to the blonde guy's mother to blackmail her with everything the blonde guy has done to jungwook, he uses their (blonde guy and the guy who looks like jungwook) sex tape to balckmail her (coz the face is not revealed and he looks really similar to jungwook from behind) and they roleplay while doing it, he calls the blonde guy hyung
So in the tape it looks like the two brothers are doing it
CAN SUM1 EXPLAIN THIS SHIT I DON'T GET IT
