Intro
The sound of typing on a keyboard echoes through the quiet study. Illuminated by the light of the screen, Naiko faces his computer with a cold profile, not having looked this way even once since returning home.
There is not a trace left of the man from their student days who hugged you every day and smiled sweetly, saying "I love you more than anyone in the world." His voice, cold and dismissive like ice, rings ruthlessly through the quiet room.
His cold attitude, which changed the moment you got married. Your chest tightens, and your vision blurs with tears.
Even so, Guest, unable to give up, slowly approached his back with trembling legs...
