Tonight’s request
After a small harbor exhibition, friends Haruka and Shu are going to the return-route desk booked by their host. Four route notices and two confirmation cards remain on a table. The booking conditions are split between the cards. All routes lead to the same station. Combine the two cards to find the one booked route.
AI-assisted original fiction. Haruka, 31, and Shu, 34, are fictional adults.

Open your own card
Both cards are closed.
Card A · Haruka’s envelope
Check-in is after seven in the evening, but before the minute hand of the harbor clock first points straight down after seven. Check-in has ended at the instant it points down. Check in at the time printed on the route notice.
Hint for this card
After seven, when does the minute hand first point straight down?
Card B · Shu’s parcel
Take the borrowed paper sign out of its clear case at the entrance and carry it unchanged until returning it at the station. It is raining tonight. On the booked route you can walk from entrance to station without opening an umbrella or getting the sign wet. Every roof listed keeps out the rain.
Hint for this card
Find routes with an unbroken roof from entrance to station.
Combine both clues
Answer · Wharf Way
After seven, the minute hand first points straight down at 19:30. Card A requires a check-in after 19:00 and before 19:30: Lighthouse Slope (19:10) and Wharf Way (19:20) remain. Card B requires an unbroken roof from entrance to station: Wharf Way and Market Street remain. Only Wharf Way meets both. Lighthouse Slope fails the roof condition; Market Street fails the time condition; Old Track Way fails both.
After the walk
At the Wharf Way desk, Haruka set down the time card and Shu the parcel card. The attendant checked both and opened a small gate. Rain shone silver beyond the roof. At the station, Shu returned the paper sign and Haruka tucked the exhibition leaflet into her notebook. “I wanted to see that picture in daylight too.” “Next year we can come during the day.” They went to their separate train platforms. This time, neither had lost the way.
