Have you really forgotten me?

Song Hyrin was just looking for some escape from being a nerd. Going with her only friend Jackson Wang( before he debut) to an underground music den. That's where she meets him. Kim Namjoon.
7 years later:
Hyrin has become successful in attaining her college degree and while attending college to become a music teacher she works as a stage manager/makeup artist. That's when she meets him again. The one and only Kim Namjoon who's now the leader of BTS. They lock eyes and she expects him to remember her but he doesn't and keeps on walking. She's hurt but she keeps moving. After the event BTS's manager comes up and hands her a card asking if she'd like to become one of the makeup artists. She agrees and forms a plan to make him remember her. There's only one thing bothering her. And that's will it work?
