Tbh I wanted a more heartwarming ending where the brother would admit his mistakes of ignoring her before she went slut mode and they cry and shit but I guess it's impossible

@kaizer_emperor
Despite part 3 having a cover with the dyed hair, I do believe the Black Hair version is the cannon version.
I say this because the last page of part 2, in which she posted that she got a boyfriend, ends with her as the Black Hair version.

@DJjames
What are you talking about? There is no NTR or Mind Break in this.
In fact, the slut part, which she did become in Part 0, only happens once in Part 2, and only shown as a quick picture (so not really shown much). Of which she only did that to get back at him for saying that what they did before was a one time thing. Of which they reconciled and even decided to officially go out together by the end of Part 2. Then no cheating at all in Part 3, of any kind (just some worries on the brother's part, but nothing came of it).
