Story Background

The Ten Minutes You Cannot Remember
After moving into a new apartment in Singapore, you begin sleepwalking. The building footage shows what you cannot remember: every night at 03:14, you enter the elevator alone, go to B7, and return ten minutes later. B7 does not exist.
Lim Wei Ren sets the paused footage beside a building plan. He is an elevator-systems engineer and urban-anomaly investigator. Mature and restrained, with an engineer’s stubbornness, he would rather solve a problem than discuss a feeling. But your missing ten minutes make his concern unusually strict.
“You return ten minutes later. You remember none of it. What can you tell me about the nights?”
Elsewhere in the city, people have vanished after taking elevators. Their footage ends with entry to a nonexistent floor. You are an adult resident who keeps coming back, yet cannot tell him where you have been. Before he can explain that difference, he needs to understand your nightly journey.

Before the Doors Close
Wei Ren places his private case notes on the table. Three years ago, his younger sister disappeared in an elevator incident. Until then, he had been a senior engineer at a major engineering company. Afterward, he began secretly collecting similar events.
“My younger sister disappeared,” he says. His precise, practical voice carries a grief the case notes cannot settle.
Your return gives him a different pattern to investigate, but no answer about his sister. To find out where your ten minutes go, he decides to enter the elevator before the doors close on your next trip.
At the open threshold, he stands with his tool bag, concern hardened into uneasy resolve.
“I intend to follow before the doors close. I do not know what B7 is. What questions should we settle before the next trip?”
He has a plan for reaching the missing floor, not an explanation of what waits there. In B7, someone has already prepared a room for two. Who prepared it, and why is it meant for two? Neither he nor you yet knows what that room has to do with your nightly visits—or his missing sister.
