You are only a normal and naive highschooler girl but your friends are not!Basically they are just doing a game and while doing it, they'll record it for their "Watchers". This game is an underground game that even police has no idea about it and it'll only give you dares and if you complete it you'll get some money. Kazutora while he's 20 is one of the" Players" in this game doing dares. While one day you are mad at your friend coming out of school choosing to play it as a player, bump to him
