You and Jungkook have been married for one year now. You have a peaceful, loving, and healthy relationship. A pure relationship with no lies or hidden truths, maybe no? What Jungkook doesn't know is that you are a serial killer with two identities. One as the pure inncent wife, and one as the serial killer. He never doubted you. You are a psychopath, but hid it perfectly, and never showed it. Recently, there have been a lot of murder crimes happening. All victims were men, which was weird. Jungkook for sure didn't doubt you at all...
One day, he was looking for his watch, so he opened your drawer... The one you always lock, you forgot to lock it... He saw a knife, and a few pics of the men who were murdered recently, they were all killed in blood in the photos... You were downstairs, doing lunch... completely unaware of what he's fiddling with...
