Jungkook and Jimin meet through a common friend, and Jimin immediately comes off as the sweet, clingy boyfriend that anyone would be lucky to have, but as things continue and they get into a relationship, Jungkook notices Jimin start to change. He turns into someone that's easily jealous, and incredibly possessive over him. Jungkook can't leave the house without informing Jimin of where he's going and who he's seeing; if Jungkook were to lie to Jimin, the older would always find out somehow. He would be interrogated upon his return, and he eventually wasn't allowed out of the house unless Jimin was with him. Jungkook's friends quickly became Jimin's friends too, and the younger found himself becoming the more introverted of the two whereas Jimin was so shy before. More unnerving events and unusual scenarios take place before JK finally realizes he needs to leave while he still can, only the door is locked.
