the reasoning is being dragged around by the short hairs in this one...
the whole setting has logic problems
i know its symbolic and a fun trope but having a charackter in a story read a book of his own story in which he resembles the charackter that read the book if his own story in which there is a charackter......
thats not just a loop thats a sign iana was already diverging from the plot before she got possessed by her creator
next having the ml arrange for the blood sister of his love to be assassinated... thats gonna put a cramp in the wedding vows and his releationship with konoha seems to have more plotarmor than he himself
the assassin that somehow forgets his task because the target is not as bad as imagined
or how he fails to catch up to her during the chase toward the uncle when he had to assume she was trying to ruin the wedding
