I have an idea.
If I pick you up to Japan when you come to Japan, we have to shorten the term you stay in Japan one day.
Also, it costs more than usual.
So, on November or Janualy, I will go to the airport and go back to Sriracha together, to tell you how to go to the airpiort and go back to Sriracha.
During this way, if you judge that you can come to the airport alone nexe time, you can ensure one day more to stay in Japan.
