If you liked the Demon Love Spell manga, the Anime-Planet community thinks you'd like:
Misao Harada has always been able to see strange creatures that are invisible to everyone else. Living as a regular high school girl, the teen wants a boyfriend more than anything, so when her first love, Kyou, moves back into the house next door it seems her wish will come true. However, Kyou is in fact a Tengu who has returned to fulfil their childhood promise and by taking Misao as his bride his tribe will gain tremendous prosperity. With other demons out for her blood, Kyou offers her protection if she will consent to marry him, but distraught by his revelation, Misao turns him down. In Kyou’s relentless pursuit to protect Misao and win her over he has begun working as her new homeroom teacher in order to best protect her. Now with demons attacking her at every turn, and a fox spirit named Shuuhei also vying for her hand in marriage, can Misao really resist Kyou’s charms forever, but does the handsome tengu really love her or is he simply after the benefits their union would bring?
