I can't hate the blondie at all. I don't know how but his pain is resonating in me. My brain be like " there must be a reason as to why he kept giving her the meds" I mean if he is really her lover, then why would he kill her right? " Additionally, the blondie priest in the persona novel, helped their country to become safe sooo I think he has a mission much bigger than himself.
But truthfully I rarely get angry or annoyed to the villains hahah, kept finding the reason behind their actions hahahh
I read some comments and saw someone mentioned about the blonde priest was the past lover of Arabella. I decided to go to spoiler forum to know what happen.
I can't hate the Priest o(╥﹏╥)o... well I'm still annoyed at him and want to punch his face tho >∆>
But I feel sorry for him because the reason why he wanted to end her because she don't want to suffer again by remembering her past of killing her own child which is Abel, if she remembered it she will kill him again. The Priest, MC, and the author are connected, they are suffered by their curse that they have to kill their loved ones.
The Priest is MC's past lover and he will keep killing her. MC will kill her child. The Author will kill his parent. Their history will be repeated, so they need to find ways to remove it.
Saw this in spoiler forum:
"They all reincarnate over and over again, remember their past memories and are forced to repeat history. The first one that killed his lover will keep loving and keep killing his lover in all his lives, he will remember every past he has and will regret each one. The second child will keep killing her children in each lifetime and has the power to know the future, when she fully remembers her past, she will kill her child again. The third one who killed his parent(which is the god) no one knows what happened to this one apparently. (he has the power to create though)"
Ugh ಥ_ಥ
Or maybe the Priest did not want to remember the pain of killing her again so he have to harden himself and kill her as to not to fall in love again or he want to end the curse by killing her then using Deborah and Abel to destroy their father so that it won't happen again in next life...well this is a theory anyway.
