What is the Korean movie Ghost Connection (also known as Humble) about?

The protagonist of the film is a pair of sisters whose parents are dead. At first, my sister mistakenly drove into a dark place, and the car navigation failed. She saw a ghost flash by. At night, she slept in bed with her sister, and something invaded her. She went to the witch for help, and the witch said that she had recruited a goat and it was hopeless.

My sister was afraid that the goat would hurt her, so she left her sister and lived alone. In order to avoid the goat, she was transferred to the night shift department and had to sleep in a busy coffee shop during the day. But my sister is possessed by a ghost. It's a goat Every night in the middle of the night, she makes love while her sister is sleeping. My sister is very scared, very painful and often in an emotional state. She always thought that her sister had abandoned her and said nothing to her sister.

My sister used to have a boyfriend. Because her boyfriend violated her, her sister called the police and her boyfriend was punished for military service. My boyfriend became obsessed and stalked after he came back from the army to harass his sister.

My sister's best friend accidentally found the goat bullying her sister and told her. Sister didn't expect that even though she lived far away from her sister, the goat found her. So my sister pulled my sister to live with her.

The ex-boyfriend found that his sister had moved, found the address of her sister's home by stealing her sister's best friend's mobile phone, and sneaked in and installed a camera.

One morning, my sister got up and found herself pregnant. The doctor said there was nothing in her stomach, but judging from the size of her stomach, she was ten weeks pregnant. My sister fainted. My best friend went to her sister's house to see her sister. My sister is going to the company, so she asked her best friend to take care of her sister.

As night fell, my best friend fell asleep in the living room. My ex-boyfriend monitored my sister's bedroom with his mobile phone and found something approaching my sister. My sister waved away in fear. My ex-boyfriend broke into my sister's house with a knife to save her. There was nothing, but she found her stomach. The girlfriend called the police and the ex-boyfriend was detained.

However, according to Korean law, the ex-boyfriend is free during the period of being accused by the court (about one month). He called his sister and threatened that he would do a lot of crazy things this month if he didn't tell him who got her pregnant.

One day, my sister came home, and her ex-boyfriend followed her with a knife and broke into the house. The ex-boyfriend thinks that his sister betrayed him and made up with others. She wants to kill her sister and die with her. In the struggle, the knife fell to the ground and was picked up by the spectre. Ex-boyfriend fell on the knife standing on the ground.

My sister thinks that the goat doesn't want his master to die, so she wants to kill her ex-boyfriend. As long as she is alive, this ghost will haunt her for life.

My sister went to the witch and tried to get rid of the ghost. My aunt said there was a way, but my sister might die. In the evening, my sister went to the house where she first saw the ghost and lit the candles and paper given by the witch. Somehow, she felt the arrival of the ghost.

Early in the morning, my sister wore pajamas and died in a messy bed in the room. The original method taught by the witch is to commit suicide when possessed by a ghost, so that the ghost will disappear with her.

My sister's life has returned to normal. She has a new boyfriend with a smile on her face. One night, her boyfriend drove her home Now she is downstairs watching her boyfriend leave, only to see her ex-boyfriend smiling at her at the intersection and disappearing in a blink of an eye.
