Minor note: His name shouldn't be Ren yet! Hopefully you can find a way to prompt user for the name that will be tossed out and replaced by Ren later, for the full effect.
Wow, you're right that it says that there but it must be an error in the original? Because, see this part here:
#t=358&list=PL8JmJYDyXnXlrwJPh3ve11lxhNBXQGw64&index=8Mariru changes his name, and it immediately changes above the dialog boxes. The name you picked and got used to for almost two whole chapters... so you feel a sliver of what Ren is feeling, "Hey, wait, what, you changed my name?! You can't do that!" A feel possible to give the reader only in an interactive medium like this.
