Yuina Sawada, 24, currently single. Her ex-boyfriend was working as a porn star (unbeknownst to her!), and by learning under him, Yuina picked up enough know-how about sex to call it a special skill; her knowledge even pulled a married couple she was friends with out of a rut! Then one day, seeing promise in her ample know-how, a young CEO selects her for the position of his sex counselor...!! She never taught him to do that, though?! This young CEO seems as sweet and earnest as a puppy dog, but he's actually a hard-as-nails [redacted]!! "Ohhh, I just can't escape him...!!"
