Light read with comedy undertone. MC is black bellied, arrogant, smart in some things and silly in others. ML is her personal guard with good aptitude, super good-looking and slightly narcissistic (he always assume master wants to take advantage of him (mol*st/flirt with him), when in reality MC have a more simlple thoughts). Their interactions is funny but not absurd. For comedy part and MC and ML personalities it can be 5/5.
But here is the biggest downgade: world doesn't work, it does not make sense. It is interstellar x ancient martial arts world, but for some reason this two genres never interact with each other in this novel.
Spoiler
People use cold wepons but fire arms, explosives, lasers etc. not mentioned even once. They have spaceships, starnet, cameras, but fight with swords and knives??? At the start MC thinks how the precise heat control can make a stronger medicine and most people can't do it... but isn't machine precision is the easiest thing in instellar era? Don't do it by hand, just use machine/robot. Why they need to have death contracts with pharmacists for mass medicine production, why not just use machines? In whole novel there is no cars (or any vehicles except spaceships), no drones. Nothing.
But if you looking for short light read with some romance and laughs and can ignore worldbuilding, this novel is enjoyable.
