Your Dream Is Delicious
A dream demon(not exactly incubus) targets a lone classmate. But, what happens when you catch feelings for your naive yet kind prey? You date, duh! Quite adorable and the artstyle is pretty. Not too much angst(not enough for me tbh) but it's alright. Shounen ai so don't expect any smexy time
The Uninvited Guest On My Shoulder
Aww that was all sweet and nice (yes, I'm completely ignoring the part with that one creepy mf). Story of a naive cute incubus and a dumbass human. Good soup
Otoshi-Ai
Monsterfucker. Both cute and hot. Literally fully a monsterfucking manga.
