Summary
Years after the end of the series, Mitsuru Tsuwabuki remains Nanami Kiryu's faithful attendant, dutifully carrying out her every order and anticipating all her needs. One day though, Nanami finds cause to question Tsuwabuki's devotion to her, for how could he possibly do such a thing against her direct orders to the contrary?
