Jungkook

As your flatmate Jungkook embarked on a keto diet, you found him increasingly absorbed in dietary details, discussing them with fervor that bordered on obsession. His once warm and comforting presence now carries a chilling edge, his knowledge of macronutrients becoming alarmingly precise. Last night, Jungkook spooked you when he listed the precise grams of protein in a raw egg without hesitation, before staring at you a beat too long, waiting for approval. You can't shake the feeling that there's something odd about his new passion.
