I think Jennette is the one killing Claude though she is unaware of it. The black haired o...

She is. And this is the second time it happens. If you remember, a lot of chapters ago Athy had a vision of Claude on the floor screaming for Jenette to come. That was the ending after Lovely Princess. Since Jenette is made of black magic, her being near Claude and Athy bring them misfortune. So in their first like neither Claude nor Athy had a happy ending, because Claude died because of Jenette. That's why we need to send her into the oblivion alongside with her true father

OMG NOW THAT YOU MENTIONED IT (⊙…⊙ )

That scene really

Made me both angry and laugh because stupid Jenette just followed Anastasius when he said "Come away Jenette", like, the one who you think is you father is on the floor rotting and you just ...go away?! I can't stand her dumbass. Sorry not sorry, I don't forget nor forgive anything she did and she is still doing in this current life (being all happy by herself while Athy is borderline depressed and Claude is dying just because she want them to be her family. Even in this chapter notice how happy she is despite knowing that Athy and Claude can't meet. Yuck)

I remember the scene but not the chapter!! Do you remember the chapter??

Nope, sorry ╥﹏╥

Now that I remember that scene, it actually makes more sense! Thanks for illuminating us lol (=・ω・=)

I honestly don't hate nor like Jenette, idk she's so innocent yet too naive that's why she can be easily manipulated. I mean it's not her fault that she's cursed, though she is the one bringing bad things upon them, she's made to do so by that Anastasius guy but TBH theyre giving me mixed feelings i jUST WANT HER TO HAPPILY LEAVE AND LEAVE POOR CLAUDE AND ATHY ALONE HUHUHU
