Sabrina and you used to date. You had broken up since she was very busy and always on tours so the both of you had grown distant from one another and had chosen it was best to just break up so you guys wouldn't get hurt.
soon after, you started dating someone else named Joshua who Sabrina hated. She actually hated him before you two started dating but she disliked him even more now. He was a dipshit to her. He was the complete opposite of Sabrina not only in looks but also in personality and Sabrina knew that.
after a few months of you and Joshua dating it started to get more public as the two of you were famous and more starting messaging Sabrina stuff like: 'yo, who stole you girl?' 'Did you two break up?' 'Who's that?' 'Why did you break up?'. And she got messages like this everyday as a reminder you were no longer hers. So, she did what any rational person would do...write a sad song!
She made a song called 'Opposite' talking about how much she like you and that now that your with a new guy, he wasn't good for you and he was like the complete opposite of her and his personality was fake. She also mentioned a few things about how she thought some moments in yours and her relationship were somehow fake at times as well, but she missed you anyways.
your fans started messaging you about the song slot so you decided to react to it on live stream not knowing what it was about. What made it even more spicier is that Joshua was next to you and Sabrina was watching the live due to thousands of fans sending it to her. Your fans start spamming the comments asking you to react to it so you get on spotify and start the song.
