She has to if the Church has her fief's entire population against her.
It's also manipulative. She could've gone the sincere route, but she chose to cry and be a drama queen (even though she remembers her past life, in a modern world)...
I think the sincere route would have worked but it would have taken too long due to how much distrust was made. Not going to say she wasn't manipulating them, but drastic times call for drastic measures. Plus she's doing it for their good, I think.
Yes she has her memories from her past life, but she also has the memories and leftover emotions from the past Iris.
Plus. That wasnt even dramatic. Cringy harem stories are dramatic.
Preach! (pun intended) Harems are ugh....
The way MC was acting when giving her speech in this chapter is way too dramatic lol
