Time trance back 10 years ago.

At that time, Qin Yujia was still a high school student, often wearing pink dresses, but her personality was slightly introverted, so she didn't have any friends.

"Happy 16th birthday, sister Jiajia" An older boy stopped Qin Yujia, who was going home alone after school, and continued: "Uncle and aunt are not here, come to my house for a birthday at night."

The boy under the sun is very handsome, and the name plate of the school uniform is clearly printed with a few big characters: Jiang Aijia.

Jiang Aijia and Qin Yujia are friends who grew up together, and their fathers are also friends, so they have close contacts.

"Okay, see you in the evening" Qin Yujia didn't see a trace of Jiang Aijia's smirk.

After school in the evening, Qin Yujia followed Jiang Aijia to the villa, there were only him and Qin Yujia in the huge living room, I don't know what it was around, and I kept making a rustling sound, which made Qin Yujia feel very uneasy, Jiang Aijia seemed to see through her thoughts: "It should be the kitten fed next door, and a group came to my small fish pond to steal fish."

Qin Yujia burst out laughing, feeling a lot more relaxed in her heart.

After that night, Qin Yujia did not go home.

It wasn't until the next day that the school called to inform Qin's father that he knew that Qin Yujia was not in school.

Qin's father called Jiang Aijia, and it was Jiang's nanny Xiao He who answered the phone: "I wasn't here yesterday and just came back in the morning, but Miss Qin shouldn't be here for a long time."

"Did Da Jiajia go to class today, can you let him answer the phone" Qin's father was obviously a little anxious, and he didn't reply all night, worried that something had happened to his daughter.

"The young master is still sleeping, the room is a little messy, it is estimated that a lot of friends came to drink last night, or I will ask him to call you back later" Xiao He was still very polite.

If it weren't for Jiang's parents who had an all-night trouble with themselves and the opening ceremony of their hot pot, they wouldn't have known that Qin Yujia hadn't come home all night, and Qin's father complained that Yang Yuan, the nanny next to him, had left his post without permission.

Can't wait for Jiang Aijia to call back, Qin's father broke into the villa, "Da Jiajia, is Xiao Jiajia still here" Jiang Aijia, who opened the door, was sleepy-eyed, smelled of alcohol, the bed was messy, and the wine bottles were scattered on the ground, obviously having no intention of going to school.

Jiang Aijia rubbed her hazy sleepy eyes, and looked surprised: "Sister Jiajia left very early last night, I said to send her back, she said that there were only a few steps away, and she wanted to go by herself."

In the eyes of Qin's father, Jiang Aijia has always been a relatively well-behaved child, except that he doesn't like to study very much, he didn't doubt what he said.

In the next few days, Jiang Aijia accompanied Qin's father to look for Qin Yujia everywhere, and the police routinely went to every house around to ask questions, and the electronic police dogs of the two families kept searching, but found nothing, Qin Yujia seemed to disappear out of thin air!

Qin's father was a very sober-minded businessman, and he seriously thought about what had happened in the past few days and found that everything was very coincidental. He locked the object of suspicion on Jiang's house, remained silent on the surface, and secretly arranged for his henchmen to follow Jiang's nanny.

Soon, Qin's father made a new discovery. Nanny Jiang and Nanny Qin go out at about 6 o'clock every morning, the two go to the same shopping mall, go to the same public toilet, and even pay and settle the bill, the strange thing is that the two never say hello, as if they don't know each other. Every big holiday, the two families spend it together, to say that the two don't know each other, it's really impossible, unless they are deliberately avoiding something.

Nanny Jiang is a very fashionable person, even if she goes out, she must wear makeup, high heels and miniskirts. Father Qin seemed to understand something.

A few days later, Qin's father called both Nanny Jiang and Nanny Qin into the room: "Tell me, when did you start." ”

"We have been together for two years and three months," Nanny Qin confessed: "Except for the weekly Monday and Friday night dates, we have been sticking to our posts the rest of the time, and we have not done anything else." ”

"Do you need to do anything else" Qin's father was angry: "Where were you on Monday night last week".

In the grove next to the Jiang family's villa...... "It is very remote there, and there is basically no one to come and go, Nanny Jiang blushed with shame, and could only pull the corner of Nanny Qin's clothes hard.

"I'm not interested in what you've done, did my daughter really leave that night?" Father Qin amplified his voice.

"Yes, the young lady left, and she left in a hurry, and Young Master Jiang chased him out, but when she came back, she was the only young master" Nanny Qin told the truth.

"You're not ...... How could he know so clearly," Old Master Qin was suspicious, and slammed the face of Nanny Qin.

"When Young Master Jiang went out, he slammed the door very hard, so we subconsciously took a look...... And", Nanny Qin paused, "Young Master Jiang saw us when he came back, and he snored us, I asked him, and he said that Miss went back and would keep our affairs secret." ”

There was no progress in the matter, and there was no flaw in the words of the Jiang family and the two nannies, and Master Qin couldn't figure out what was going on with all this after racking his brains.

One day not long after, Father Qin, who was asleep, was awakened by the sound of a siren, and he suddenly had an ominous premonition. He looked out the window and saw the nightmare of his life, a girl in pajamas sitting on the window edge on the top floor of the villa opposite, her hair disheveled, her clothes disheveled, her hands constantly tearing and throwing something like paper, and then falling.

She was Qin Yujia, who died on the spot.

The villa had been abandoned for a long time, and there was only one house that showed signs of habitation, and there were some changes of clothes for girls, handcuffed and handcuffed all over the floor, and mottled with blood. The police speculated that Qin Yujia was kidnapped and imprisoned, causing a mental disorder, as for who the murderer was and how she fell from the building, because there were no fingerprints and special smells in the room, the police had no clue, and this temporarily became a headless case.

The results of the forensic examination were that the vocal cords were seriously damaged and unable to pronounce, that he had been severely violated before his death, that he was severely depressed, and that the fetus in his womb had been formed, which was about 4 months old.

After the funeral, Nanny Qin and Nanny Jiang resigned one after another, probably because they felt that they had not done their job well, which led to the accident.

2 years later, when Qin's father was cleaning Qin Yujia's room, a card USB drive fell out of a book in the bookcase, not because of the lack of pages in the book, the USB drive would not fall out at all, the photo on the card was Qin Yujia looking at his father and smiling, Qin's father palpitated. He inserted the card into the Phantom headset, which contained three videos.

Father Qin opened the first paragraph, and inside was the tearful Nanny Qin, who was mottled with blood on her body, and it should be in his living room.

"Mr. Qin, when you see this video, I shouldn't be there, I'm sorry, I hid some facts......"

The card has been broken, and it is completely unclear what Nanny Qin said in the back, and it can be seen from the blurred picture that he is full of guilt and repentance, and the next two videos have also been completely destroyed.

Realizing that the situation was wrong, Qin's father hurriedly contacted Nanny Qin, who was far away, but unexpectedly learned that Nanny Qin had been suspected of murder, and the reward given by the police was to brutally kill his wife and son who was less than one year old.

The police found Qin's father and told him a truth that made him break down again.

The confetti that Qin Yujia threw from a height before falling from a building came from a book called "Nanhua", and after the unremitting efforts of the serious crime team, the 700 fast fragments were finally restored to 10 pages, and a complete fingerprint was also pieced together on it, from Qin Nanny, according to which Qin Nanny was locked as a suspect.

Father Qin opened the book that Qin's nanny gave him again, and found that the book was missing exactly these 10 pages. However, he couldn't figure out why Nanny Qin would harm his daughter.

Soon, Nanny Qin was arrested, and public opinion was overwhelming, and he didn't make any quibbles for himself, feeling that everything that should come was going to come sooner or later.
