Gran promised he would return to her no matter what. So even though people mocked her for being single and “past her prime,” she continued to wait faithfully for him. But when Gran finally comes back, he has lost his memory… He has completely forgotten Sheila—and worse, he’s turned into a total jerk!? “Well then… if that’s how you’re going to be, fine.” What action will Sheila take? A romantic battle of wits between an amnesiac knight and a devoted yet strong-willed apothecary girl!
