It seems a to be a nice story, with a good world and interessting characters. The backstory of the concubine is tragic and the reborn version is instantly likeable. But that the backstory is partially unknown gives the story tension, that is needed.
The characters around him are also likeable, hopefully we see them develope. The adding of new characters is a bit fast, but it is okay, if it didn't continue with the pace it is going. It would be to many characters to keep track of.
The englisch is sometimes a bit iffy, but it is mostly tolerable.
