Sofie is in a relationship with Jungkook. They were actually really happy, till Jungkook started to act different. He wasn't affectionate or loving anymore, it was like he never loved her. It seemed strange to Sofie, because nothing happened between them, that could trigger such a twist in their relationship. Thats why she started to make a little research and what she found out, broke her heart even more. Thanks to her boss Taehyung for holding her in times like this, when she feels like the whole world is against her.
