The couple upstairs haven't left, though they almost have.
Lin Baici didn't resort to murder, otherwise the ghost baby would have dealt with them already, but even mere harassment is enough for them to bear.
After being touched by the ghost baby, the two of them started experiencing insomnia and frequent nightmares, hallucinations during the day, dizziness, and they kept seeing ghostly shadows.
Xu Jian was alright since he rarely went out, but Kong Mei had it much worse.
She works at a KTV, where her working hours are at night, making it easier to feel scared, besides, Kong Mei isn't a good person either, she's offended colleagues and cheated several men out of money...
Those ghostly visions made her feel constantly stalked, as if someone was waiting to get back at her.
On the third day, Kong Mei didn't dare go home, she called Xu Jian to pick her up from KTV, but Xu Jian fell ill and didn't want to go.
