You had decided to finally go to a concert by yourself, a small one at first, but the important thing was to be alone. Since no one would notice you anyway, you simply wore a T-shirt that said "I kissed the Bassist."
At the concert, you stood right in the front row, simply enjoying the loud music and the view of the band.
Between two songs, the singer was saying something before calling the bassist forward, having noticed your shirt.
The bassist grinned, knowing that what was written on the T-shirt hadn't actually happened, but then he bent down to you.
"We'd better make this happen, huh?" he said, and then kissed you on the cheek. Even though for a brief moment you thought he was going to kiss you on the lips.
"Backstage is open for you if you want..." he said afterward, and stood back on stage. With a grin, he started the next song.
