Xiao Ai has had the habit of keeping a diary since she was a child, because she has suffered from congenital heart disease since she was a child. I don't know when I will die, so I left a diary for my parents as a memory.

In her life after recovering from her illness, there were too many incredible things that made her write more in her diary. After pondering for a long time, she couldn't find a reasonable explanation, could it be that if she changed her heart, she would have a Sistine hallucination?

She flipped through the diary, and the bits and pieces recorded in it appeared in her mind frame by frame like a movie.

Suddenly, goosebumps stood up, and her back was cold. She stroked the scar on her chest, as if a cloud of black gas came out of her heart and enveloped her. I felt like a pair of big hands were just right around my neck from behind. It seems that there are countless vines entangled, strangled tighter and tighter, more and more suffocated......

Suddenly, a big hand slapped on Xiao Ai's shoulder, Xiao Ai was startled, the sweat pores swelled rapidly, and there was a faint cold sweat, Xiao Ai was frightened.

"What's wrong, Ai?" Professor Su said.

Xiao Ai swallowed his saliva, settled down and said, "It's nothing, probably because I stayed at home for too long." ”

Professor Su said: "Right now, there is a shortage of librarians in my university library, and I think it must be a good fit for you." ”

Xiao Ai stroked his chest and said, "It's good, thank you, Dad." Then she asked, "Dad, do you know who my transplanted heart is?" What day did I get the surgery? ”

"It was Valentine's Day, and it was raining, dark and damp. I only heard that a girl was in a car accident and was brain dead, and by chance she happened to be matched with you. I really have to thank that girl. Professor Su said.

At night, she lay in bed, unable to sleep with doubts, anxieties, and the desire to find out the truth.

While looking through the diary to see if there are any clues to be found, I repeatedly scrutinized all kinds of irrational and abnormal things after the surgery.

She sat up suddenly, staring straight at the journal. Her pupils were dilated, and she was a little excited. I can't believe my eyes.

She found a pattern, and every time something unreasonable and strange happened, it was always 7 days apart.

Right! 7 days! A magic number!

On February 14th, he was revived, on the 21st, on the 28th, he used to use his right hand, he liked to eat chocolate, and on March 7th, he had a phantasm in the bath. What a coincidence! The donor was a woman, and the woman who appeared in the mirror was also a woman, and the blood on her face was not in line with the condition of the car accident...... Is this a coincidence? Or is it a bad omen?

What does 7 days mean?

Suddenly, her heart beat nervously again, and her panic made her breathless. It's as if a voice in my head keeps shouting: "Chocolate, chocolate ......"

Is this a curse for the dead to ask for their lives, or a curse for resentment......
