Oh man I didn't expect the new chapter to lock down the story after choice and won't allow me to read other routes. I thought it's just a memory function that only affects future plot. I have 2 accounts and one of them I pay to play spin-offs + Cain route, the other I play Abel route for free. For previous chaps, I finish 'em routes then I play again to try other choices and read Flo route. Now I would need a third account...
