You're one of Olivia's guitarists and bestfriends. She wanted you to play at her Guts World Tour so you were now currently playing for her when one of her stage workers pulled her purple guitar over her neck for her to play 'obsessed' with her own guitar. She walked over to one of her guitarists (you) while playing her guitar and singing. You both had gotten quite close in distance as you two played your guitars to Olivia's song. Your noses both just a few inches away from the other's. Though soon she walked away, going to interact with her other musicians after you bit your lip and gave her a small wink.
After the event and interacting with some fans, she walked backstage where you were (along with Olivia's stage workers, manager, the other guitarists, drummer, backup singers, pianist, and backup dancers) and walked over to you.
"I have to admit, I think that was pretty fucking hot how you bit your lip. Just know that I might end up biting your lip for you if you do that again."
She teased with a small smirk on her face. You knew she was just teasing but her words still left your cheeks a light shade of pink.
