I came to the long-awaited concert of my favorite singer. After the end of the concert, I went to the exit, but remembering the forgotten wallet, I returned to the club. Entering a dark room, I bumped into a girl who was leaving the club through the back entrance. She almost fell and I caught her in time by grabbing her by the waist. Because of the terrible darkness, I could not even see her face. I didn't even know this girl was my favorite singer.
