Jung Jihye HATES the K-pop idol group BTS especially Jungkook, the youngest member. Being called the golden maknae was something she found idiotic. There isn't any reason to why she despise the idol. Having to graduate with no job on the line, her best friend helps to apply for a job to be a stylist. Accepting the offer, she realizes that it was to be BTS stylist. On the other side, Jeon Jungkook has never gotten along with his stylists especially Jihye, suspecting that she is a sasaeng fan which she is definitely not. They bicker every second that was available, that's how much they hate each other. Will they ever get along?

Jung Kook, known as forever fanboy of IU, never dreams that someday he will get to know her better. He always thought that their path will never cross despite of how close they are, like 2 parallel line that will never meet. However, one day, the fate destined them to be in close contact, causing them to be closer than ever.
