On the 38th week of her pregnancy, Kazama's baby is born with neonatal asphyxia-and on the 26th week of hers, Ide's child is born extremely premature. They're admitted into the NICU at the same time, and neonatologist Dr. Shirakawa is assigned to Kazama's baby. Believing it to be a case of persistent hypertension, Dr. Shirakawa begins treatment anew...but progress is slow, and soon he finds himself hitting a wall.
