I feel like Evan and the accusing posse was enchanted somehow by that "Saintess" Sandra... I also think that she was the same girl that caused Taki to get sick. Taki said that she had a black heart, so maybe she has ties to black magic ?? If that was true, then it would make sense that someone as loyal as Evan would accuse her of doing those things, and why now he's thinking twice about what happened.
And ik it's a stretch but. honestly. I think the true Saintess is Lana ! They said that the Saintess' abilities awaken before they are sixteen, and Lana seems to have healing magic of some sort. (That explains why Tito could heal so quickly + how those ppl said her food is more healing)
Last thing, I think that in the past, she might've met with the other prince before and they must've gotten engaged...but somehow she ended up forgetting ? That's why that prince called her "Lana" and helped her as much as he did even though she was his brother's fiancee. (He's the one calling her "Lana" that's why she didn't allow Evan to call her that as well)
And of course, thank you for the update !
