Read: Ch.13
It‘s way too simple, weirdly paced and cringe with so many plot holes, as if a ten-year-old chils wrote this after reading some shoujo stories with similar settings.. it‘s no hidden gem, just badly written.
MC is a slave pretending to be a count’s daughter and brought in as ML‘s new concubine, because all his concubines died so far due to assassinations ordered by the empress dowager and the princess, who‘s wants to be ML‘s next empress (they‘re cousins btw).
ML is a dragon and several hundreds of years old.
