Late at night, Ah Chen lay on her bed when the door of her room suddenly resounded with a knocking sound.
She got up and took a look, then called out, "Who's there?"
This villa was hers alone, connected to another slightly smaller villa next door where the butler and maids lived. It was easy to reach them, a phone was enough, not inconvenient at all.
The sudden knocking on the door in the middle of the night was indeed eerie.
After Ah Chen spoke up, there was no more sound from the door.
She lay back down to continue sleeping, but the knocking sound resumed.
She got up, cautiously approached the door from behind, and yanked it open. Naturally, there was nothing outside.
Then she turned on the corridor light, accessed the corridor surveillance with her phone, and lay down again.
Knock, knock, knock——
The familiar knocking sounded once more, Ah Chen picked up her phone to check the surveillance, finding nobody at the doorway.
[This is terrifying.]
