looking for a chinese webtoon manhwa title. transmigration/reincarnation. FL restarts her life from the past or her sould enters a new body. she is made to marry a prince who is said to be dumb, but as the story progresses ML slowly shows that he's more capable intelectually than he leads on as well as talented in the martial arts (but only to the reader). her goal is to ruin the crown princes life, i think. FL is a doctor too, i think. FL and ML are really in love and are lovey dovey. ML is a simp and FL is more aloof and mature. one arc: they went to a village and cured people of their sickness, but they were supposed to fail and get in trouble. FL has dark black hair? and blue eyes. ML has brown hair and brown eyes.
A korean webtoon about a girl who is either transmigrated or regresses in time. The story stars off when she is young. She is a powerful elementalist/summoner. There is a woman, who could be her step mother or former nanny, who is evil and betrays her to kidnap her. She gets out by summoning a spirit of nature that looks like gaia. She was also on a mission to fill a contract with another spirit, who is a old male ice spirit in the mountains. I can't recall much other than this arc and stuff, just because there are so many similar child manhwas with regression/transmigration. Also, no, this is not "The Golden Haired Elementalist".
Korean actress transmigrates into another world. FL has black hair and purple eyes. ML has white hair. They pretend to be lovers and FL has to teach ML how to act as a proper lover. This is all to find out the person who has been killing his previous fiances. A potential suspect is a blonde-haired girl who covets the duchess position.
