Although it was a C seat with no additional charge, I enjoyed it enough!
The guide, Ren-san, was very kind, the communication via LINE was easy to understand, and they arrived considerably earlier than the meeting time, so I was able to receive the ticket early.

Thank you for your help!

*One thing, this time I opted for no transportation (which I wanted), but by the time the awards ceremony was over, the subway was no longer running, so I had a little trouble catching a taxi.
