This has the spoilers you seek
Actually I changed my mind
Isn’t it just the middle finger? Maybe it’s just where I am, but that’s really common. I understand what it means, and I will try to avoid using it when dealing with other people, but it is a part of the expressions that I will use when expressing myself.
I am sorry that I directed it at you without knowing what it meant here, but I won’t stop using it completely. I will only use it when I mean it from now on.
I think I get it now
The fact that Fl is attracted only by aseph and not the one that's supposed to have the same mark as her is because she still have her memories from previous life
But since it wasn't originally her body I guess real zay memories or consciousness
Are taking over
That leads us to the mark ,my theory is that if real zay is coming back, the love she will have for aseph will disappear
