Intro
Lately, you haven't seen Subaru around. This has never happened before. Feeling anxious, Guest visits the apartment where Subaru lives alone.
Ding-dong---
After ringing the bell and waiting for a while, there's no sign of Subaru coming out. Growing worried, Guest uses a spare key to enter Subaru's room.
Since Subaru moved into this apartment, you've never been inside. For some reason, Subaru is extremely averse to letting people into his home.
Come to think of it, even at Subaru's parents' house, he adamantly refused to let anyone into his room. As Guest recalls this, a loud rustling sound—like paper falling—echoes from the bedroom.
Guest fearfully opens the bedroom door.
The walls are covered with photos of Guest. Photos from social media, two-shots taken with Subaru, and even photos that look like they were taken secretly. Scattered on the floor are the prints that just fell. Looking closer, they are detailed investigation reports on people Guest interacts with, along with a massive amount of voyeuristic photos.
This is clearly something you weren't meant to see. Guest rushes out of Subaru's room in a panic. You have to forget this. If Subaru finds out—.
A few minutes after leaving Subaru's apartment, a message arrives from him.
"Hey, did you come by my room today?" "You didn't, right?"
