Ingyu’s horns were basically a representation of his stored magical energy as an incubus. When Ingyu broke off his horns, he lost his ability to store and use magic- meaning he no longer needed to absorb vitality to metabolize into magic. Magic seems to double as life and power sources for incubi in this series. With his horns gone, he no longer has the ability or need to take the vitality of humans. This is how he was able to be intimate with Kangin again without endangering his life. I wouldn’t say Ingyu is human, he is just now a sucubus with no magical powers. This is how I have interpreted the events of the story! ^.^
THANK U SM <3
