If you use this code for selecting the mc name you don't have to tell the reader the default name. Instead you just set it automatically if the user didn't input anything.
```
shiva "I'm Shiva, and this here is my brother, Ash."
show ash shy with dissolve
ash "Hello..."
you "Hmmm... my name?
# "The main characters name is White, you can place your own preferred name ^^"
$ maincharacter = renpy.input("What's your name?", length=32)
$ maincharacter = maincharacter.strip()
$ maincharacter = maincharacter if len(maincharacter) > 0 else "White"
mc "It's [mc]."
```
