Compilation of short stories, all but the last one are about the same couple.
Binetsu Shuukan (Week of Mild Fever)
Wakui Satoru is a senior staff in the company who looks out for Asano Keiji. The moment he saw the handsome Wakui's naked body, Asano's heat welled up within him. The pride of someone older, the seduction of it. The heated heart that desires to monopolize... the love that wants to be stripped bare. A fever that only happens once in a lifetime. A considerate seme who is a younger salary man.
