The sacred night of lovers... Christmas is a time I want to spend with you... With a pained expression, Ichika let out those words. Our meeting was about two and a half years ago—she was the secretary for an important client, and our relationship began professionally. But before long, it evolved into something more. It started exactly six months ago, one summer evening after work, when we happened to run into each other at a bar in Nishi-Azabu. Our conversation drifted from work to personal matters, and the distance between us rapidly closed. Since then, we've been meeting every two weeks, building a mature relationship. I would arrive later at the hotel where she checked in, and we'd steal brief moments together until dawn, sometimes even spending the whole night. On those rare occasions when I could stay over, she'd beam with happiness. As the nights deepened, sometimes lasting until morning, we devoured each other's bodies, confirming both love and deep carnal desire. And then she said those words to me—the ones at the beginning. I never expected her to say such a thing, knowing full well that a relationship between us could never truly work, given that I have a family. Has Ichika, no longer satisfied with just my body, begun to desire my heart as well? A forbidden relationship between a man and a woman, sinking into profound darkness. Their long, passionate night has only just begun—and shows no sign of ending.
