Houseki no Musume to Inou no Ouji

Anna, who grew up abused by her stepmother, is sent on an apprenticeship to a mountain castle where Evan, a prince with a dubious reputation, lives. Being the newcomer, Anna finds herself in a difficult situation as she is snubbed... but it is Prince Evan who saves her! A prince who closed his heart because of his ability to "read people's minds" and a kind-hearted maid. When these two unfortunate people meet, the wheels of fate begin to turn! A love fantasy of desire, hidden conspiracies, and love over the "Legendary Jewel" begins! https://www.cmoa.jp/title/264944/
