Funny that saves got mentioned, I messed up again, fell for exactly the same thing as the Rin/Chika lock out, but in later content (I was a fool and didn't play it smart around a certain choice that once again puts me into a future red event) and am now back at the start (per my own personal rules, if I ever get something marked red or confirmed in a state where I will be seeing something marked red in the future with no way to stop it from happening, all my saves are to be deleted and I restart from the beginning, no exceptions). This marks the 30th restart since the beginning of development that resulted from a first time through an event, a point at which I would not have had the notes I do now. I have had no restarts off of events I have watched more than once, I have notes to prevent that.
