An Incurable Case of Love seemed to me to be almost a rewritten version of Itazura na Kiss. The two heroines are very alike, cute, a bit klutzy, well-intentioned, kind-hearted and seemingly deluded in their pursuit of a cold, egotistical but genius guy. Both series partly or mainly have a hospital setting. Both leading females choose to become nurses in order to pursue their love object, with the guys both being or ending up as surgeons. If you can't get enough of Itazura na Kiss, the charming An Incurable Case of Love is what the doctor ordered.
Narratage is also a student teacher romance, although most of the story takes place after the female student has graduated.
