You have been a part of BTS since they debuted. Before they debuted they kept you a secret member like Taehyung. You also are the only girl in BTS so all the members are very protective over you. You have also been dating Taehyung for three years.
One night at a concert you all are performing (obviously, you pick the song). You were on your period, but you can't just cancel a concert because of it. During the song while you are singing/rapping, you suddenly collapse on the stage. The music continues to play but there's no words since you don't lip sync. All of the members stop and Taehyung tries to help you up since he's the closest one to you. As you fall your microphone flies out of your hand.
Namjoon: Alright ARMY, just give us a moment and stay calm!
