Stairway to Heaven

Narumi Imai has been with the FBI in Washington DC for six months, and already he has been recognized as the best man for... odd, chore-like jobs. As much as he wants to work in the field, his first opportunity comes under a bizarre set of circumstances. Narumi is the personally chosen bodyguard of Keith Coburn, a former FBI agent brought in from prison to HQ just seven days before his scheduled execution. Both Keith's mission and life have a time limit, and for the next seven days, Narumi will be his companion on the stairway to Heaven. Source: DramaQueen Extra chapters from Last Portrait.
