Manga The Unfeeling Me

Lou Lang was once a man. Now, having lost his monthly memoirs, he awakens to find his skin cool and white, with a frightening thirst for human flesh - talking more briefly, he somehow became a zombie! His classmate, An Baichu, seems to be the only one who knows about his condition, and he does not give this information without a price. He puts a collar on Lou Lang and makes a great offer to him if he kneels and begs. Despite the fact that he is the subject of Baichu's research, difficult emotions appear, which are all destroyed when it seems that he is involved in the deadly transformation of Lou Lang...
