"Life is a game of turning away from the dull routine." Tajikun and Yukie from Anzayagi, along with Kaoru, are trapped in a prolonged period of sexless relationships. Living together, they grow increasingly distant, with no outlet for their emotions. Even if feelings still remain, the timing never seems right, and opportunities slip away, day after day. One day, sensing Yukie's absence beyond the window, Tajikun decides to invite a delivery health worker while she's away. His decision to break the stagnation of daily life and seek new excitement sets the story into motion.
