Private Nurse: Maria

Hiroki has suffered for years from an unknown illness. Due to his weak constitution, he is unable to live like a normal schoolkid and often has to depend on his best friend Ayano to take care of him. When he can attend school, he often spends most of his time in the nurse's office. Ayano cares for Hiroki more than she is willing to admit, and Hiroki repeatedly pushes her away due to his embarrassment at being unable to "be a man" and fend for himself.
