Margy.1997's Manga

There's a lot of stuff missing in this compared to the book and heaps of changes. In the novel Eren never takes of his Armour and her rival is actually a business man that hires people to scare customers from going to her shop. The novel also has more views of Cedric and his thoughts about Ariel. The manwha doesn't show that the perfume he needs is becoming less effective yet he seems to cool his bloodlust around Ariel - this happens around the time he becomes her invested. Highly recommend you read the novel for this one
