Meh, it's far too convenient for FL so far. I am all for a revenge plot or whatever, but this is some serious BS if you give all the power to one character.
ML is far more intriguing because he is constantly struggling with morality and self preservation. This would have been better if FL was treated as the trap that ML had to protect himself from while helping her overcome her own demons, instead of her being the MC fucking up everyones life just for not speaking up.
But I feel this will go another route now that the annoying Ex who should have no reason to be involved with ML, is getting this push. In which case, it'll just be another edgy revenge plot which would suck cuz there's been too many of those recently.
