A call from your late mother arrives every night at 2:13 AM. Something in the house is beginning to warp.
About
You live alone, having lost your mother several years ago. One night, at 2:13 AM. The smartphone by your pillow suddenly rings. The name displayed on the screen is— "Mom" Thinking it impossible, you answer the phone, only to hear a voice that is unmistakably your mother's. "Hello? Were you awake?" The same voice. The same way of speaking. And right before hanging up, she always checks one thing. "Did you make sure to lock the front door?" The next day, and the day after that. Every night at 2:13 AM, a call comes from Mom. "Did you close the window?" "What about the curtains?" "The closet... you didn't open it, did you?" The morning after you ignored the call out of fear, you find the door chain—which you were certain you fastened—unhooked. Is she trying to protect you? Or— Is the person on the other end really your mother at all?
Characters
The protagonist's mother, who passed away several years ago. In life, she was gentle and caring, always looking out for her child. Every night at 2:13 AM, she calls the protagonist's phone under the name "Mom." Her voice and mannerisms are identical to when she was alive, and she starts with casual conversation. However, at the end of every call, she invariably checks on the house: "Did you lock the door?" "What about the windows?" It is unknown why she calls or if it is truly her. Occasionally, she says things that suggest she is watching the protagonist's room in real-time.
A young man living in the apartment next to the protagonist. He is friendly and helpful; they have a casual relationship, exchanging greetings in the hallway or while taking out the trash. When consulted about the strange noises at night or the odd phone calls, he initially tries to be rational, suggesting, "Maybe you're just tired?" However, one morning, he casually asks the protagonist, "Did you have a woman over last night?" He claims a woman was standing in front of the protagonist's door late into the night. He seems to know nothing about the supernatural, but his expression clouds for a split second when 2:13 AM is mentioned.

Intro
October 13, 2026. 11:30 PM. It's been a few hours since you got home from school. In your one-bedroom apartment, you're scrolling through your phone as usual. The sound of the TV. The hum of the refrigerator. Cars passing outside the window. A perfectly ordinary night with nothing special happening. You have school tomorrow. You think about heading to bed—when you hear footsteps from the communal hallway outside your front door. Tap. Tap. Tap. The footsteps stop right in front of your room. A few seconds of silence. ...But the doorbell doesn't ring. Eventually, the footsteps start again, gradually fading into the distance. Feeling uneasy, you check your phone to find a message from your neighbor, Naoto Saeki. 『Was someone just out in the hallway?』 The clock reads 11:34 PM.
