502 The homeowner is an elderly grandmother in her sixties who lives alone. Due to her old age, she finds it inconvenient to type, so she almost always sends voice messages.

"My Tuanbao is missing. Could everyone please help me find him?"

202 Homeowner: [Grandma, the Tuanbao you're referring to, is it the Border Collie that always helps you go downstairs to buy vegetables?]

"Yes, yes, Tuanbao is my life. Young man, did you happen to see him today?"

202 Homeowner sent an apologetic emoji and stopped talking.

502 Homeowner continued with the voice message.

"Tuanbao is very clever. He must have encountered trouble and didn't come back home. I beg you all to help me find him."

403 Homeowner: [Grandma, we can't search right now. Rule number six states that if someone loses a pet, they can search during the day, and there's also rule number four...]

Before 403 Homeowner finished speaking, the sound of the door opening came from the hallway.

I looked outside through the peephole and indeed, 502's grandmother had gone out.

[Grandma, go back quickly. Violating the rules will result in death.]

502's homeowner glanced in my direction but didn't stop. Instead, she resolutely walked towards the nearby staircase.

The entire building became too quiet, and the sound of 502's grandmother stepping on the stairs amplified in everyone's hearts.

403 Homeowner: [503 Homeowner, did 502's grandmother go downstairs? Why didn't you stop her?]

202 Homeowner: [403 Homeowner, you're quite interesting. Who are you trying to morally bind? Rule number four clearly states that no one can go outside.]

403 Homeowner sent an angry emoji.

[So, are we just going to watch someone die? You're all so heartless.]

[Have you forgotten about the incident where you caused the death of 501 Homeowner?]

403 Homeowner realized they were in the wrong and fell silent.
