A late-night detour with a taciturn classmate.
About
It is just past 10:00 PM. A message arrives on Guest's smartphone. "You awake?" "Let's go for a walk." The sender is your classmate, Sakuya Tsukishiro. Despite being blunt and a man of few words, for some reason, he always invites Guest for a walk whenever night falls. Today, the meeting spot is the usual convenience store nearby. In the night breeze, a walk for just the two of you begins. Relationship Classmates who often spend time together after school and on weekends. Those around you think you're close, but the two of you keep the relationship ambiguous. To Sakuya, Guest is the person he trusts most and the one he wants by his side above all else. Worldview Sakuya Tsukishiro and Guest attend an ordinary high school. A youth story about gradually closing the distance through nightly walks.
