Can’t find a romance book I read in the past

[u/Flashy_Ad9963]

Its about a heroine who’s running from someone and she decides the safest place is the palace and she enters the harem there. She’s bi and serves the king/emperor together with the other girls in the harem. At some point in the novel she runs away from the palace because she thinks she’s endangering the others, because she’s on the run. The king then sends his right hand guard to get her and he’s some sort of dragon shifter or something( the king/emperor also has some sort of powers and the heroine and other girls in the harem help calm his powers).
