A trilogy of books written by Konohara Narise and illustrated by Saikawa Nanao. The chronological order of the trilogy is ''Cold Sleep'', ''Cold Light'' and ''Cold Fever''.
After Tohru loses his memory in a car accident, Fujishima gives him a place to stay. Fujishima claims that they are friends but due to his reticence in talking about Tohru's past, Tohru is suspicious of Fujishima's motives for helping him.
!!Contains these tropes:
* AmnesiacDissonance: Happens twice. The first time when Tohru finds out that he used to be a violent man, and the second time [[spoiler: when Tohru looses his memory of the seven years after the incident.]]
* TheAtoner: Tohru.
* BastardBoyfriend: Averted at first, but then played straight later on.
* StockholmSyndrome: The relationship between Tohru and Fujishima feels like this by the end of the trilogy.
