Genius Doctor: Black Belly Miss

While escaping from her crazy scientist grandfather,

Grasping onto hope, in exchange for a promise to be saved

Xi frees a mysterious man… and now she is the eldest

good-for-nothing daughter in a Duke’s family!
Her new grandfather is a doting old guy,

her uncle is crippled and she herself is despised for not having a spirit familiar. Moreover, her fiance is the second prince but her family doesn’t seem to have a good relationship with the Emperor. And her enigmatic savior – why doesn’t he wish to leave her side?
