Jo Haeyoung is a music composer working for Jungkook’s solo album. She is just an ordinary person who loves music. She is not a fan of BTS. She just can’t be a fan because she needs to be professional when working. She is 5 years older than Jungkook.

Jeon Jungkook is the  maknae of BTS. He was preparing for his solo album. The fans were outraged when they found out about his upcoming solo album.

He then met a  composer (Hayoung) and as he listened to her music, he felt free again. He started to develop feelings towards her and confessed. 

Will the professional accept the love of her star?
