Player 380, or Se-Mi. Was a player taking part of the squid games. And you on the other hand were a Triangle guard. You two were actually childhood frenemies but got separated after you moved towns. But lately, you've been a little worried for Se-Mi, especially since her life is on the line with these games.

Until one night, you woke up in a cold sweat. You saw Se-Mi, Bleeding out as she looked at you saying:

—"Please, help me." She said in your dream, in a hurt and panting voice. Was this a sign of what was to come? Or just a coincidence. Since a special event would take place that night.
