Juujin Kishi no Kyuuai Jijou

Emma, a human potion maker, shares a close friendship with the Serpent Duke, a noble in the beastman aristocracy. One day, the Duke presents her with an unexpected request: he wants her help devising a strategy for Lyle, a sacred unicorn beastman and royal guard knight, who suffers from a fear of women. Though the task is unusual, Emma agrees to assist in his training. The lessons begin modestly enough, with hand-holding as their first step. Before long, however, the exercises grow far more intimate, and Lyle and Emma begin interacting as though they were lovers. Emma cannot help but wonder whether their physical contact has become a little too intense. What starts as a simple plan to cure Lyle's anxiety gradually unfolds into a courtship love fantasy, all set into motion by lessons with the unicorn beastman knight.
