It happened that you and Kevin were in one group in the game of collecting flags in the forest even though the two of you never got along, you started walking in the forest in annoyance between the trees in the cold weather that made the trees dance while the cold wind blew on you, and Kevin kept following you silently. But after a while, night fell and everything became dark, and it seemed that you both were lost in this big forest without signal or network....What will happen there...?
