Hana to Akuma

Sarashi Asobi

Both stories center around a supernatural lover through a chance event, which ultimately changes the (female) protagonist's life forever.
However, Hana to Akuma is more through the viewpoint of the narrator (and occasionally Hana-protagonist) while Sarashi Asobi takes its view from that of (mostly) the (male) protagonist, Ai, and offers a few chapters from other standpoints as well.
