Jimide Medatanai Watashi wa, Kyou de Owari ni Shimasu (villainess story)

I have confused something here. If the power of healing that Sanbra used to prove that she is a saint was the power she stole from Taki (I was wrong and switch the name with Shin. I always mistake their name between these brother)  didn't that mean the saint should be Taki?

Does anyone spoil me about this? 

Is it a first prince who had not a black hair one, right? 

Wait, doesn't miko mean priestess? So is he actually some kind of head shrine maiden descendant?

Summary: Elaine Lana Norris, who was born at the top of the aristocratic daughter, was declared abandoned by her second fiancé at the school's founding party. Lana, who has been made a villain daughter, is driven out of her home by a strict grandfather.
But there is a secret in Lana that everyone doesn't know about?

I don't have any spoilers, but here's what I have so far.
- Lana was set up by the heroine who's quite frankly a 2-faced bitch who tries to steal MC's shit. Try because she's caught by the MC drops and breaks it and insists on kneeling in front of MC and cleaning it with her skirt. MC is all "??? There's cleaning stuff right over there you know?" This is where the accusations began once her fiance the Prince finds out.
- She never loved the Prince but had great affection for her childhood friend and protector. He was seduced by the Heroine and man-handles her in the "conviction event."
- She is driven out by her grandfather because he felt he was lenient too lenient on his son for marrying a foreign Princess.
- So as to make her example drives her out to her grandmother's place where she is being treated like shit by her cousins for having her engagement broken.
- MC decides to have enough and slips out of ala "I'll Live My Second Life!" and changes her appearance dramatically via makeup. Made sure to bring money with her she ends up buying an Inn. 

Thanks for the follow up spoilers! especially on new data with gramps but I'm confused with MCs powers thing? In the manga, she was somehow able to heal facial injuries of some sort?

Oh and don't worry about the vocabulary thing. Its still readable/understandable and you got your point across. There's always room for improvement. 

Whoa! Hold on with all that anger gurl. At the beginning, sure I was rooting for first prince and was kinda disappointed with early spoilers in the thread that Shin might be the ML (since you know, the prince and her family are working hard to fix her rep, prince is childhood friend in this timeline that had to be mindwiped for some reason, and 3. since you all know my conflict with MCs gramps, it just rubs me the wrong way whoever he's betting on who ends up with his granddaughter)  but recent update on the adaptation proved me I could live with Shin endgame (actually lets be honest, man who can cook is better than a man who has barely a status. But the first prince isn't a bad character so the hate is unreasonable). I mean, MC prefers her commoner life and shows no interest in wanting to be back in nobility, she spends more time with Shin since most of her POV happens outside the noble circle and more on her Bed and Breakfast/Inn, its been spoiled here they'll kiss, the shared 3 lifetimes, gramps approval, better in-laws compared to the royal fam (I mean, his two sons got sick and for some reason, the king doesn't give a sh*t? Her in-law if she goes with 1st prince is the 2nd prince who manhandled her once on the anullment event and shows no regret?) since Taki himself is a looker. 

Tbh, I wonder if it's in part cause of the culture thing. Respect elders and all that which is far far more emphasized in the east than the west (though not saying it isn't in the west). If so, I still think that' derp. 

I seriously hope they are not. If they are this whole story had everything to be great but will end totally dumb? Like since day one girl wanted a peaceful commoner’s life and now you are telling me her choices are first prince or royalty descendant? Life for real? What is the author even thinking at this point
