What's the story of the third person played by Gao Yuanyuan?

It feels like a parasite.

Zhang Rong and Zhang Xiaochun are brother and sister, and their age difference is 10 years old. Since childhood, their parents have been hurting their sister Rong Zhang, but they have neglected their brother Zhang Xiaochun intentionally or unintentionally. The reason is human nature. The couple have been married for many years and have no children, so they adopted their younger brother. Unexpectedly, a few years later, they gave birth to their sister. One is adopted and the other is biological, so the treatment of brothers and sisters at home is naturally very different. Every good thing is mainly about my sister, and the focus of the whole husband and wife life is also around my sister. For example, my father is a photographer, so all the photos at home are taken by my sister Rong Zhang and his wife, and Zhang Xiaochun only helps to press the shutter. Because of this, my brother Zhang Xiaochun was very unhappy when he was young. He often plays truant, runs away from home and wanders in the street. As time went on, his parents became more distant and disgusted with him.

One day, Luo, a gangster friend, was cornered by debt because he owed money outside, so he moved his idea to his home and went home to steal money while playing truant. When they were looking for the family property, they didn't expect to be found by their father. After a fierce fight, their father was pushed down the stairs. The two of them set a fire at home and then fled in panic. As a result, the fire at home didn't reach Zhang Rong in the naive class, but it accidentally killed their parents. Of course, he Luo also ran away later, and the murderer was never found in the whole murder case. At that time, Zhang Xiaochun came across his father's new camera while stealing. He took it in a fit of pique out of the motive of making trouble, and then sold it to Cheng Cheng, the senior of the school photography club at that time, for a little money.

All this was nearly twenty years ago. Now Zhang Rong is 24 or 5 years old because he has a brain tumor in his head. Now he takes medicine and injections every day to fight against death. And her brother Zhang Xiaochun, after what happened at home, disappeared out of thin air for more than ten years, turning theft into robbery and robbery into murder. But it suddenly appeared a few years ago. Now he is pursuing Rong Zhang's good friend He Le, who grew up together in an orphanage, to get married. Zhang Rong, of course, had no doubt about him. Her brother was really kind to her when he was a child, and now he le's lover. The affection between their brother and sister naturally recovered. The only thing that made Zhang Rong feel a whisper in his heart was that after years of separation, their attitude towards each other became very polite and recognized.

The real thing started when Zhang Rong worked in a courier company. Because of a delayed package, she met a man who came to pick up the package, a man who got drunk in broad daylight and acted decadent. His name is Cheng Cheng. Maybe it's fate. The similarity in their lives makes them feel at home. Cheng Cheng committed suicide by cheating on his lover. His serious guilt drove him to want to live and die several times, so he drank and got drunk all day. Zhang Rong has an untimely bomb in his head. I don't know how long he can live. Zhang Rong saw the camera in a second-hand grocery store run by Cheng Cheng. Because her father has a habit of carving his initials "Feng" on the camera base. Zhang Rong proved to be correct. But she doesn't know how the camera was lost after the tragedy reached Cheng Cheng. Cheng Cheng said that his middle school sister sold it to him very cheaply. The boy doesn't know his last name, only that his first name is "Koharu".

Twenty years ago, when Rong Zhang was very young, his parents died suddenly, and his brother was away from home all day, and he has since disappeared. In her memory, there are only various things pieced together by relatives and neighbors, and she doesn't know the whole story at all. Also because there are too many "Koharu" in this world. So she doesn't have any interest. In the boring life of taking medicine and injections, she began to investigate Zhang Xiaochun, He Le's lover and brother step by step. Could it have something to do with the tragedy at home? She explored her brother's original figure and habits intentionally or unintentionally. Finally, I even arranged for my brother and Cheng Cheng to meet unexpectedly. See if this Koharu is Peter Koharu? But for too long, Cheng Cheng's memory of looks is very vague, but he said it was probably not. Because what he remembers (the classmate who gave him the camera), Koharu, his right hand was badly burned, and he even played billiards with his left hand for a long time. And Rong Zhang's brother Zhang Xiaochun's right hand is completely natural and normal skin, and plastic surgery can't be so good. This seems to rule out the possibility that my brother Zhang Xiaochun has something to do with what happened at home.

But Zhang Rong was more afraid. Because she really remembers what the love affair said, this story about her brother Zhang Xiaochun, and even remembers the cause and effect of why the boiling water burned her brother. And now my brother Zhang Xiaochun's right hand, why not a scar? She really wants to ask. So, when He Le was away on business and Cheng Cheng was drunk, she found her brother Zhang Xiaochun and showed him the camera to see how he reacted. Therefore, Zhang Xiaochun guessed that it had something to do with their father, but he didn't know that his father was used to marking cameras. Sister knows, brother will not know? Then who is this man? Who is this man who calls himself Zhang Xiaochun?

Zhang Rong has another way to force out the possible truth of the matter. In other words, this seemingly normal brother Zhang Xiaochun actually has a very abrupt psychological phobia in his daily behavior. He is afraid of "sharp things". Sharp objects of any shape and appearance will stimulate his vision, further affect his brain and nerves, make him very sick and uncomfortable, and even incite violent tendencies. Of course, Rong Zhang knows nothing about psychology, but He Le once showed her a Hitchcock film "Doctor Edward". It describes that the protagonist incites obsessive-compulsive disorder because of guilt, forcing himself to pretend to be another dead person and enter the other person's life mode to continue his life, so as to comfort his guilt. She wondered if it was the status quo of "the man in front"? Moreover, it seems that only by facing up to his phobia can we reveal the truth of what happened twenty years ago.

So, Zhang Rong borrowed a Gu Jian from the love affair to deal with Zhang Xiaochun. In fact, the truth of the matter is often difficult to ask. Unless you are sure to face the possible sequelae after the truth is discovered, moderate ambiguity is the way to continue to survive. Rong Zhang didn't understand this, and her life time didn't allow her to continue to be vague, so she paid the price. Zhang Xiaochun has a sister with a brain tumor, but ironically, this person seems to have a healthy head, but in his heart, there are two people. One is biological and the other is parasitic. In fact, Zhang Xiaochun really died to save this man, so he thinks he is Zhang Xiaochun.

There, Nick Cheung also plays an insurance salesman. He also bumped into someone in it and helped her get an insurance policy, but the child was adopted and his father didn't want to treat him. He thought of a miserable year in Zhang Xiaochun, so he helped to get a fake insurance policy to treat the girl.

So I feel that this is imitating that, but I don't understand other people's plots!
