well, I mean they diiiiiid kind of push her past self to commit suicide, so
It would've been better if the original owner's of the body were to take revenge for themselves rather than Su Luxia to make this feel like they gain more justice by doing this but ofc they wouldn't have the experience for taking revenge nor have any ways on actually making it happen since they were really affected by the situations that made them feel really depressed (at least for some of them). Tho Su Luxia is a big help on redeeming these girls and turning them into something greater than they originally were but it feels kind of bittersweet since it's not really them or their own accomplishments. It's someone else's that's taking their appearance and background.
Oh boi sorry for the whole essay but I really went deep into introspecting this whole manga pFFT- IT'S STILL GOOD THO
No, I totally agree with you on that entire spiel.
I feel that the punishments Su Luxia gives to ml and fl is too harsh to make her morally right tbh. I like it though.
