This is a story I encountered when I went to the bank to make a deposit.
At that time, I was sitting on the lounge chair waiting for my number to be called. I was looking through my almost full inbox, intending to manually delete some spam messages. That is, when I found the seventh or eighth message, the conversation between the two girls sitting with their backs to me caught my attention.
I listened carefully, and I saw a slightly older girl with a steady voice with a sigh, and another girl with a clear, green voice but vaguely mute, who was the protagonist of this story.
