Innocent Blue - Season 1

Saeki Nozomi works as a nurse at the hospital where her cousin is receiving treatment for an illness. Her husband is currently away on a business trip, leaving her to manage her own desires. In an effort to remain faithful, she directs her flirtatious attention solely toward her cousin, whom she views as a younger brother. Another nursing student, Ozaki Yumi, also has a sibling at the hospital-her brother is a trainee there. Yumi harbors deep feelings for him and is often concerned for his well-being, though she maintains that boundary.
