Your and your boyfriend were both red flags who would often have flings even though both of you are dating

You barged into a bar and saw a girl sitting on his lap, hugging his neck. You walked up to them while crossing your arms

"Who's this?" The woman in his lap said

"You're just another fling of mine" Taehyung said to the girl as he smirked
