Rules of the Plum Rain Season

[Rule-Based Horror + Chinese-Style Horror + Later Survival Chase. No abusive folk customs like ghost marriages or reincarnation pills. No golden finger. The main cast is all female. The protagonist seems depressed, but she's actually ruthless.]

One day, An Wei, a resident of Sunshine Garden, found a strange list of rules stuffed through her door.

1. Keep your doors and windows tightly shut to stop strange things from getting in. The only safe time to open them for ventilation is from noon to 2 p.m.

2. Clean your dehumidifier at least once a day to prevent bad things from growing inside it.

3. Leaks from the ceiling and peeling paint are normal. Don't panic, unless gold and silver jewelry starts falling out. Remember, pies don't fall from the sky.

4. If you hear rustling or tapping inside the floor, bed frame, door, or ceiling, don't panic. It's termites, not ghosts.

There are no man-eating evil spirits in this world, so don't worry. Just contact a professional pest control team or use termite-killing fungi.

5. It's normal for things to grow mushrooms during the rainy season, but if the mushrooms start talking to you, do not answer them. No matter how cute or understanding they seem, their instincts are parasitic.

6. Fungi are very cooperative and share plenty of information. You can always trust the bonds of the mycelial network. If they consider you a friend, they'll be honest with you and do everything they can to help you get what you want.

7. Mold is very common during the rainy season, but try not to stare at it for too long, especially don't try to make out faces in it. If you see a mold patch that happens to look like a face, don't go closer to identify it. The more carefully you look, the clearer it will become. And don't scream, or it will remember your voice. Wipe it away with disinfectant and a dry cloth. If that isn't enough, contact a professional mold removal team.

8. Don't panic if you see flowing red liquid, unless it forms a shape by itself. If you see moving red footprints or another shape, don't approach it or scream. Cover your mouth and nose, hold your breath, and walk around it slowly. Don't run. It won't bother humans unless you attract its attention.

9. Watch your step, especially on the stairs, and don't walk too fast. Go slowly, preferably holding the handrail. Don't make footsteps or scream. Don't let it hear you.

10. Don't wipe the condensation off the mirror. If the condensation in the mirror begins to clear on its own, or something that shouldn't be there appears on the mirror, close your eyes immediately or cover the mirror with something opaque. Sit with your back to it for ten minutes before leaving.

11. It's normal for people to slip and call for help during the rainy season, but before helping, make sure the person who fell is actually human. Normal people don't eat wood or iron as snacks.

12. Whenever possible, record these rules using materials that won't run. Within seven days, the words will also be blurred by condensation or eaten away.

We wish you a safe ten days during the rainy season.

She thought it was just a prank, until an announcement said that a serious kidnapping had taken place in the residential complex and that it would be sealed off for ten days while they searched for the victim. No one was allowed to leave. At the same time, everyone in the residents' group chat said they'd received the same list of rainy-season rules...
