Hiromi, the protagonist, is being ostracized simply because his puberty is delayed. Worried about her son, his mother knocks on the door of a certain hospital, clinging to a sliver of hope.

What kind of hospital has he been brought to?

The name of the hospital is Daijuji Hospital, and the department is… the Virginity Department!? Is virginity something that can be treated!?
