Secret Lady
This is really good, but the start is painfully slow so you have to give it a chance, it WILL get better! A girl who can see ghosts isekais into a novel girl that can also see ghosts. She hears of the impending death of a prince she met as a child from a ghost and goes to help him disguised. Turns out that his family is cursed? The specifics are hazy because I was reading too fast and the translation was a bit off, but his ancestor married an ethereal being who granted his wish on the condition only one child of all following generations would survive. Our lad has a brother. The ethereal being's ghost or whatever says to our lad as a child that he will break the curse but he can't love anything, as everything he loves will disappear, and she indicates backwards to the sleeping figure of our MC. So he knows who our girl is, despite her disguise. She's yet to share with him that she can see ghosts. The costumes are interesting, sort of a bastardised version of medieval attire - hose and all. It fades away a bit as the series goes on into something more modern.
