【What's the matter?】

【It's about this old man, the owner of the apartment, who goes to a certain place every day.

This place seems to be underground in the apartment.

And he stays there for almost the whole day.

I felt curious, so one day I went to chat with the old man during the day.

In our conversation, we casually talked about this, and that's when I found out that the apartment actually has a basement.

As soon as the basement was mentioned, the old man became very alert and asked me why I brought it up.

I was afraid of raising suspicion, so I didn't ask further.

But I could sense that there must be some secret hidden inside.

So one night, I secretly went to the basement to find out the truth.

Who would have thought that the basement was locked and couldn't be opened at all.

However, even though the lock didn't open, it attracted the monster.】

【Ah? It attracted the monster? What happened next?】

【After that, I desperately tried to escape.】

【Did you die?】

【What do you think?】

【I had already recorded before I set off to explore the basement, but there was no continuation after the recording.】

【That means you died.】

【Yes.

Although I didn't find out what secret was inside, there must be a secret.】

【So this time, we need to find out the secret in the basement?】

【Yes, it might be our only way out.】

【Then tonight, shall we continue our actions?】

【No, it's useless. That lock can't be opened. Even if we try a hundred times.】

【Then what should we do?】

【I have another piece of information.】

【What is it?】

【Every time the old man goes to the basement, he brings a key with him, and this key is taken from his bedroom.

So to go to the basement, we have to first go to his bedroom and get the key.】

【Where is his bedroom?】

【On the second floor.】

【That's great, he's in the basement during the day, so we can go get the key.】

【Susu, are you stupid?】

【Ah?】

【If the key is in the bedroom during the day, how does he go to open the basement?】

【Oh, right.】

【And, during the day, the rooms on the second floor are all locked.

Only at night, he returns to the bedroom.

So, to get the key, we can only wait until he's in the bedroom at night.】

【Ah?】

【Also, there are three rooms on the second floor, besides the owner's bedroom, the remaining two are the study and the restroom.

I don't know which one is the bedroom.】

【Wait, Huihui, I'm a bit confused...

Are you saying that we have to go to his bedroom at night to steal the key?】

【It's you, not us.】

【Wh-What do you mean?】

【I can't leave... the door to my room is locked, and I can't open it from the inside.】

【How is that possible?】

【Maybe the owner of this apartment noticed something and locked me inside the room.

Unless I find the key and open it from the outside.】

【Ah?】

【So, Susu, now you can only rely on yourself.】

【Not... If the owner is in the bedroom at night, won't I run into him?】

【I've already thought about this problem, and there's a way to solve it.】

【What way?】
