by the way, I forgot to say, that when I was going to the exit (arena's exit), I saw a staff member who was standing at the counter. I was walking slowly so I noticed flowers, some bags and a glittering bag with words "WE LOVE ZIN", then I stopped and asked if I can leave here a present for ayu, she immediately smiled and said "yes, of course!" and showed me her hands, but I said "awww no, I'm sorry, I don't have it

". and then asked if we always can leave a present after a concert and she said yes. jesus, I wanted to stay and write a letter at least, but that would be so lame, so I decided to prepare a special present next time. there wasn't a lot of presents... I'll definitely make something next time
