The Protagonist's Resignation Letter

Found a sticky note in my manuscript. Not my handwriting.

'Chapter 23: I confess my love to Sarah. Chapter 24: Sarah dies. Chapter 25: I grieve. Chapter 26: I meet New Sarah. Chapter 27: I confess my love to New Sarah.'

'I'm not doing this anymore. Find another protagonist. I'm moving to the villain's subplot - at least he has consistent motivation.'

Signed: Your Main Character.

P.S. 'The sidekick agrees. We're unionizing.'
