If the address is like this

esp == 00000000

esp + 5 = 00000005

esp + A = 0000000A

00000005 can contain only one byte character.

Isn't it correct that only one byte of text can be included in 0000000A?

This syntax takes the value in esp+0x5 and compares it with 61.
There must be something in 00000005.

But why does the comment show a string when I got the esp+A address and put it in ecx?
Shouldn't ecx have an address corresponding to esp+A annotated or just one byte value corresponding to 0000000A?
