I need underrated dramas! I mean ACTUAL underrated dramas. Not the same ten dramas people call underrated but good dramas that only a few people say they know about or have seen. Can be Chinese or Korean.  

A good rags to riches story. Something where they all of a sudden are living in luxury. Like bae Suzy’s Anna. Not necessarily a Cinderella trope just something wear there is a diff lifestyle. Preferably the FL. But not where this is all done by the ML. Also like heard it through the grapevine.

Rich kids. Not too bratty but I want the drama centered on the rich. It doesn’t haven’t to be over the top but can be just their everyday life. Nothing too infuriating.

couple with a unique bond. Not a trope but a couple that really acts like a couple besides the shyness and lovey dovey stuff. Again just normal day to day couple. Not boring though.  

It's historical but maybe Colourful Bone? It's very underrated, rags to riches (ML goes from a slave to emperor. , SML is the prince and therefore a rich kid, and the leads have a unique bond.
