My Boyfriend is a Monster Vol. 4: Under His Spell
Bethany Farmer is far too practical for cheesy high-school romances. That is, until transfer student Allein shows up. He acts just like a character out of a cheap romance novel, but to Bethany's horror, she is completely smitten with him. To make matters worse, Allein turns out to be the heir to the throne of Faerie, and he's being hunted by savage creatures who want his throne for their own!
