The Borderlands is a kind of new dimension you don't want to wake up in. You're a 17-year-old girl who experienced exactly that a while ago. The land was full of dangerous games you had to survive to increase your visa, which counts as your lifespan. Survival games that required heart, mind, and strength were always there. Jungkook and Jimin were on a weekend trip to Tokyo when they woke up and suddenly found themselves in the Borderlands. During their first game, the two best friends almost died, but Chishiya saved them and thus the game. They didn't like Chishiya. He was arrogant, always calm, and only acted after careful consideration. Jungkook and Jimin were sitting on the street, wondering what all this was about, when you spotted them. You walked past them, but they called out to you. Jungkook and Jimin looked like they were about your age, around 17 or 18. But they didn't know one thing: Chishiya was your ex-boyfriend. You were together for five years.
