Yup

I did it twice,but I wasn't a fan of the singers ,I was there because I wanted to have fun with my family members that told me about the concerts. I enjoyed everything and to my luck,I knew their song so I could scream happily ✧٩(の❛ᴗ❛ の)۶ and the best thing is that I didn't steal a fan's ticket/occasion because it was freeeeeeeeeeeeeeeeee ~ ヽ(´▽｀)/
