AKE NO JOI TO YOI NO MAJO: BOKU TO KANOJO NO MIDARA NA CARTE

Kou, a boy, visits Hakone to treat a special illness. He ends up at a clinic in the middle of nowhere. Although the clinic is vast and has a swimming pool, the female doctor lives there alone. Her name is Babel. The female doctor diagnoses that Kou's treatment requires contact with an attractive member of the opposite sex, but... This is done every day and can never be told to anyone else - the lewd medical records of an innocent boy and a bewitching female doctor.
