I just thought so since the main theme is high school and ORC related. Plus mostly in cases where romance is there they usually use the "passing out togeather" concept. And she's a devil so mind manuplation is no big deal, especially when fallen angels have a large scale memory alteration device. Her father is also one of the founder's of the academy she can get into Kuoh college whenever she likes. One year is nothing for a devil after all.
