I was skeptical with the cliche introduction of his type seeming like the playboy type but as simple as it is I liked the development plot of him being attracted to a dense beautiful refined girl who's "manlier" than him in the sense of chivalry.
I'd like to see this become a manga to see how he slowly attempts to make her fall for him even though he only just got her heart to flutter by looking cute to her by being vulnerable. The fact that he's a demon may be an interesting conflict in the future. 7/10.
