the boys got out of the army, but you hadn't seen them yet because of your solo tour. It was your last show, it was in Korea, Seoul specifically

You had just sung your song Seoul City, which you had done to your boyfriend Namjoon. You were admiring the audience, until you spoke to the audience

"I'm going to sing a song that I love by BTS. Spring Day, I wish they were here with me. My hyungs that I love so much.."

So, you start singing the intro. Until, one by one, the members came from behind the stage, singing with you...
