THIRD PERSON POV

Rosé knew she had fucked up, she knew you had heard her interaction with Taehyung & it pained her how harshly you had spoken to her. What you told her about being a fling had her heartbroken, she didn't want that. Only now she regretted what she had done earlier with Taehyung, she knew how badly it must've hurt you seeing her with your ex boyfriend. She however didn't continue being with Taehyung after your interaction earlier. She just watched as you were having fun, messing around with your friends & her cheer mates. That could've been her she thought..

You finally got out of the pool heading towards the kitchen for another drink, you weren't drunk nor tipsy yet your tolerance for alcohol was pretty high. Rosé had took that opportunity to try to talk to you again, she followed behind you to the kitchen, "Y/n please let me explain. You're not just a fling I want it to be much more than that! I promise you." You listened to every word she said, but just shrugged & stayed quiet. She was only sorry she got caught, "Y/n please talk to me. I'm truly sorry! I promise you, I want more with you!" You exhaled & walked up to her backing her against the wall making her think you were about to kiss her, "You're only sorry you got caught!" You spat out bitterly, "I was a fool to think you weren't like the rest, but man was I wrong." You scoffed, backing away from her.

"If you really wanted something serious you wouldn't have been fucking around with Taehyung & would of at least tried to respect me. But no. I hope you find the one because I'm not it. Whatever we had going on is over, don't bother to call or message me because you won't get a response. Only do so if it's an emergency with my mom or your dad." You say bitterly before exiting the kitchen back to the party putting on a fake smile for everyone.

Rosé exhaled feeling her heart in her stomach. The one person she really wanted to take serious was gone, just remembering the amazing date you two had on Monday made her realize how she had lost an amazing person. She realized how respectful you had been & never once tried to actually sleep with her on the first night. Tears welled up in her eyes as she deeply regretted it all. She wished she could back in time & make sure she never interacted with Taehyung in the first place.

——————————————————————

Thursday rolled around, the homecoming dance was on Saturday. You knew that there was going to be an after party after the homecoming dance since it ends very early. You had a game Friday if you won that means you'd play against 2 other teams. You were planning on asking Rosé to go with you to the homecoming dance but that wasn't going to happen now. Not after what happened yesterday at Jimin's party, instead you'd ask Yunjin, she was charming, goofy, good looking & nice. Plus you had plans to go out after your game on Friday, your mom had also warned you in advance that she'd like you to join her, Hoon & Rosé for brunch Saturday which you happily agreed to do. Even tho she betrayed you, you weren't going to let that get to you & ruin your relationship with her father.
