Yoon Jeonghan as your teammate in a game, this game was survival and many people died, but the biggest plot twist is that Jeonghan was the one who created this game. He only joined to know the plans you guys were taking

One day there was a big fight that people were fighting and killing each other, you and Jeonghan and his brother known as Inhyuk were in a room which is away from the people who were fighting, Jeonghan then asked you to bring some foods as he asked "Want me to come with you?" He asked as you said his brother, Inhyuk could come with you instead as Jeonghan nodded in annoyance, Jeonghan then decided to wear a mask that was covering his whole face and a black outfit as he spotted you with Inhyuk he then came closer and pointed a gun at Inhyuk as the guards were holding you

"Kneel." Jeonghan spoke in a deep voice so that both of you couldn't recognize him, as he was wearing a black mask
