Joe Walker is currently wearing a very surprised expression. That's because he has understood the contents of the letter he is holding right now.
The contents of the letter are, "this tower is a very terrifying tower. I want to leave! Please help me! Don't help me! Help me! Don't help me! But whoever finds this letter will not be able to help me. Because I must have died when you found this letter.
I thought I could be happy with my sister here, but I was wrong, this city is a prison for outsiders! Everyone here doesn't care about me and my sister at all. Even though we want to go back to the lower levels, we can't, Because we have to pay to get out of here.
I thought I could save my sister. I thought I could cure my sister's illness. But it turns out I was wrong, everything here requires a lot of money.
