you and Hyunjin are in a happy relationship but Hyunjin started to suspect you of cheating so he gave you a small silver/gold necklace, you were happy and immediately put the necklace on, not knowing that this small, inconspicuous necklace has a camera through which Hyunjin can see what you are doing. Today you went out with your friend to the mall not knowing that Hyunjin is now sitting in front of the computer watching carefully what you are doing through the camera in your necklace
