Medical student Song Qingshi has just awakened inside a historical fantasy novel and bestowed a mission: save the protagonist from a life of slavery.

There's just one not-so-minor problem: Song Qingshi doesn't read historical fantasy and has no idea who is who! So, instead of correctly identifying and saving the protagonist, he's actually just rescued the brilliant and beautiful minor antagonist, Yue Wuhuan.

Yet not all is lost. Rather than being put off by Yue Wuhan's suspicious interest in poisons and villainy, Song Qingshi makes it his mission to treat the underlying trauma to reform his "heroic" ward. United by their love of medicine and a budding mutual attraction, the two must face a hostile and fantastic world in a fight to give Yue Wuhuan the happy ending he deserves.
