All of you hating on her need to sit the fuck down and take a chill pill. You all do realize she was placed in this world out of her insane love for him to give him a second chance to not have a tragic ending?
1- The MFL previous never had a twin so she was created for the purpose of fixing this shit.
2- Whatever powers that be gave her a crest and for reasons which are unknown to any of us right now but has a purpose.
3- That being said the crest is the reason why she's losing her mind. She's in turmoil she expected to be able to love him as she did before she became Zay with no issues no problem. Even if she would not be the one he falls for she made his happiness her only fucking job. She's loves him so much she's broken up and losing her mind to the point she almost gouges out her whole chest....
4- She's hiding the crest because of the rules that come with such a thing she realizes if he knows he will make himself into a demon to have a crest like the last time and the end will be the same.
Even if she declares her love he might still end up either killing an innocent man or going the demon road to have the same crest as her and that A BAD END.
Am I the only one concerned about Nine aka Brother Thorton? I hope he comes back and actually assists with the plot.
Don't worry, If I remember correctly he will come back in the next chapter or in the one that follows it (so in 1 or 2 chapters).
And he's the ML so don't worry, he will be part of the plot.
