The center of the mystery is the character Luca, who apparently uses magic to manipulate the memories everyone in the manor so he can live there without question. But there is no excuse, no backstory, no hidden identity surrounding this character. He looks exactly like the ML with different color eyes, but is not suspected to be a relative. He dresses like a knight but doesn't perform a knight's duties. In the beginning he only appears when the Duke is gone, suggesting dual personality, but then he shows up at the same time as the Duke. And the MC just does a poor job of trying to figure it out, not even directly asking the Duke about this person's existence.
[collapse]I also don't like how characters' emotions would transition unnaturally.SpoilerOne day the daughter hates MC, the next day she decides she suddenly likes MC, in a tsundere way. One minute MC says she absolutely won't leave, and the next she's left because... honestly I can't pinpoint a substantial reason why, only that the Duke told her to leave in a sad rather than angry way. One minute the Duke stubbornly hates her and doesn't believe anything she says, no matter the evidence she piles, then she disappears he suddenly misses her and thinks she's right.
[collapse]But if you're willing to suspend belief for the mystery and sudden character changes, it's a good read and interesting story overall.
