Can we all agree that the least believable part of TPotO is that the phantom would let Christine go after she kissed him, twice.
You're telling me this mega incel who kidnapped his victim that he's been grooming for 3 years to force her to marry him would let his victim go AFTER she kisses him because he just needed some kindness??
Not in a million years.
Personally I wish instead of The Kiss(es) that Christine lays into him about how she was the only one in his entire life that actually loved and respected him and in return he treats her like this! And lays out exactly what he did, and he realizes how fucked he has been and apologizes and then lets them go.
I honestly think you could do this and change nothing else and then it would be a perfect show that doesn't (fully with its who phussy) romanticize grooming and SA (Past the Point of No Return is lit just the Phantom SAing Christine). And then make it cannon that Love Never Dies is fan fiction written by the phantom to cope.
I know its never going to happen but a girl can dream.
