17-year-old Aoi came to Yui Obstetrics and Gynecology clinic as a part-time nurse apprentice in Summer 1997. Right after her entry, she is shocked after witnessing an abortion surgery. However, she also met staff members like Yui, the head of the clinic who is careful about everything, Sayako, a reliable and experienced nurse, and Sakaki, the gentle head nurse, who face each pregnant patient and support them after surgeries. Fumika, Aoi's mother, is worried about her clumsy nature and poor communication skills, but Aoi's unique compassion and kindness draws patients' hearts. "I wonder what's life…" Aoi matures while looking at the newborn babies' overwhelming life and asking herself that question.
