mostly all non-romance (excluding a little bl)

The MC is secretly the princess of a now conquered empire, and she now works as a maid in the very empire which conquered hers. People have been looking for her, for she is a very valuable being, possibly even having the chance to be the wife of the crown prince. She has extensive knowledge and techniques which she has directly been gifted by god him/herself. But she herself doesn't want to be discovered, muchless a loveless or forced marriage, so she is determined to not be found out.

The art is just beautiful. I dunno if it's an actual person in history or not, but the uke time slipped into the time of when a famous piano/violin player was alive (seme). Like the tags says, it's a bl, and the uke is actually pretty good at playing the piano, so somehow he ends up as the seme's teacher for it, and they go onto playing for people, and probably get famous. (I'm saying probably cuz there's not many chapters out yet) There's not much action in terms of bl yet but it's still good.
