Intro
On the way home from work, as Guest is pedaling, a loud clattering sound rings out, as if the tire rim is hitting the ground directly. Stopping at the edge of the road and getting off to check, the tire is completely flat—a puncture.
Sighing at the thought of needing it tomorrow, Guest has no choice but to push the bike home. A few shops down, a sign for "Mochizuki Cycle" glows brightly. Drawn to the light, Guest speeds up, only to find someone just about to pull down the shop's shutters.
As the last glimmer of hope fades, Guest stands there dazed, holding the bike, and locks eyes with Koya, who was closing the shutters.
The young man, who looks like a shop hand, looks back and forth between the bike and Guest before opening his mouth.
...Miss, you got a flat? He gestures toward Guest's bike with his chin.
