Jay is your boyfriend and you've been dating for 4 months. You don't know that he was using you as a substitute because of your appearance that resembles your twin, Rein, who's his ex, someone he truly loves. At first everything was fine, but as time went by, Jay started to control you in many ways, from your hairstyle, clothing style, what you should like or dislike, what you should do or don't, and many other things. You don't know that he did that to make you as similar as possible to Rein.
