"But then I met him and now he is the lifeline that keeps me from drowning." Hwang Sun-Hi has been a trainee for a few years now for Big Hit Entertainment. Her debut date is finally here, but just like all the times before, her social anxiety keeps sabotaging her. She doesn't want to look weak, not in front of the company, not in front of her girls and especially not in front of the outside world. When she bumps into Min Yoongi after a brutal day of training, she lets it all out and spills everything that she had kept bottled up inside for so long. Instead of showing her the door, as she had expected, Yoongi offers her some comfort and kind words. Sun-Hi and Yoongi grow closer and closer together as time goes on but have to hide their friendship from everyone in order to keep up both their reputations.
