Nana and Xiaohong are a pair of very good friends, the two are inseparable every day, and they are together everywhere they go, like twin sisters. Both of them are dormitory students, living in the same dormitory, although the environment is relatively simple, but the small dormitory is full of warm atmosphere.

In the dormitory of four people, the relationship between the two of them is particularly good, so good that the other two girls wonder if they have something, but they don't care, and privately agree to be good friends for life.

One day Xiaohong was sick and stayed in the dormitory to rest, Nana went to the cafeteria alone after class to eat, because she had to eat for two people, so she ran to line up as soon as possible. There were a lot of people, crowded around, and a tall and thin boy in front of Nana lowered his head and played with his mobile phone, not noticing that the person in front of him had already walked forward, and hurried forward when he reacted.

At this moment, two people suddenly ran not far away and happened to pass in front of the tall and thin boy, and he braked sharply to avoid a collision, but Nana, who was following behind, was unlucky. didn't react, and hit the boy's back, and the boy was also hit, and the lunch box in Nana's hand was scattered to the ground in response, and Nana was pushed by a reaction force and sat on the ground. The boy looked back while touching his back, and at a glance he saw Nana sitting on the ground with an embarrassed face, the boy was stunned, and then quickly stepped forward to pick up the things on the ground, and then helped Nana who was sitting on the ground, and apologized vigorously in his mouth.

Nana, who was helped up by the boy, was a little angry, her buttocks hurt hotly from this fall, and she was about to get angry, and when she looked up, she bumped into the concerned gaze of the boy, and she was also stunned. The two looked at each other for a few seconds and then quickly moved away, Nana felt a strange feeling in her heart, feeling that her face was hotter, the boy reacted quickly, kept saying sorry in his mouth, and continued to line up with Nana's lunch box in his hand.

The boy was very polite, helped Nana with food, and sent her back to the girls' dormitory before turning around and leaving. Nana didn't know what was wrong with her, and when she walked with the boy, she felt an indescribable sense of satisfaction, the boy had a beautiful face, a tall man, and a faint scent of soap on his body, which fascinated her a little. Back in the dormitory, she didn't share the experience with her friend Xiaohong for the first time, and even when she was eating, she was still a little distracted, and Xiaohong called her for a long time before she reacted.

In the next few days, Nana seemed to have been poisoned, her brain was full of the figure of the boy that day, and she would often giggle, which made Xiaohong very confused, and once thought that she was infected and sick. Fate is a wonderful thing, once at dinner, after they bought the meal, they found that there was no place to sit, so they found it in the cafeteria, and saw two empty seats from a distance, Xiaohong pulled Nana over quickly. After grabbing the position, Xiaohong "giggled" at Nana, Nana also looked up in response, and her expression gradually solidified with a smile, because she found that the boy sitting opposite was very familiar.

"Haha~ Hello, see you for the second time, my name is Akai."

The boy who was being stared at saw Nana as soon as he looked up, first stunned, and then greeted her with a smile, Nana was still stunned, until Xiaohong's coughing woke her up, and Nana hurriedly responded.

"You... Hello! My name is Nana. ”

As soon as the two started talking, they chatted unconsciously, which made Xiaohong on the side have a black line in her head, faintly unhappy, and the two left each other's contact information after the meal, which made Xiaohong even more unhappy.

Love is like a Pandora's box that has been opened, and the relationship between the two has also heated up rapidly, at first, it was Xiaohong who accompanied her, and slowly, Nana began to deliberately avoid Xiaohong to meet the boy alone. This makes Xiaohong, who has no friends, often alone, and becomes more and more dissatisfied with Nana in her heart, so the two have several big quarrels, but Nana, who is deeply in love, doesn't care at all, her heart is already full of love. In this way, the two fell into a cold war for the first time, and this was also the first time that the two who had been very good since high school had a conflict.

Sometimes there must be a fate, everyone's fate is predestined, even couples in love will have times when they quarrel. Nana cried and ran back to the dormitory, the other two roommates happened to be there, seeing this, they all hurried forward to comfort, Nana's mood improved slightly, and suddenly found that Xiaohong was gone, and the roommate said that she hadn't seen her for two days, probably asking for leave. Nana is very strange, Xiaohong is a single-parent family, and she usually doesn't ask for leave, why did she suddenly ask for leave, and a bad premonition slowly rose in her heart.

In the afternoon, Nana went to the rooftop of the school alone, which was where she and Xiaohong used to come before, and it was also their secret base, and there were very few people who came here. Nana's eyes widened in horror the moment she pushed open the rooftop door, and a moment later, she let out a terrible cry for help, and followed her line of sight, and there was a female corpse lying on the ground not far away, with her face facing the rooftop door. Her eyes were full of unwillingness, her seven orifices were still bleeding, and the whole corpse looked a little blue, and she was Xiaohong, who had disappeared for two days.

Soon, the doctors and police arrived at the school, Xiaohong's body was carried away, and the police left soon after taking notes, and Nana never recovered from the panic just now. For the next few days, Nana was in a trance, sometimes feeling that Xiaohong was nearby, and the body she saw that day was not her at all, and it was all just a dream. When they were inseparable, they often sat back to back on the lawn of the school reading books, and the sunlight was scattered, and she enjoyed the fragrance of books, grass and air blending together.

Walking alone on the way back to the dormitory, Nana was thinking wildly in her head, and from time to time she took a big breath of air, as if she wanted to find that taste again, and take a few more greedy puffs. Suddenly, she felt like someone had slapped her on the shoulder, and Nana immediately stopped and looked left and right, there was no half figure around, but it felt very real and familiar, like a dead little red.

On the seventh day after Xiaohong left, Nana took leave to lie in the dormitory to rest, and the other two girls went out because of something, and she was the only one left in the dormitory. Extremely tired, Nana soon fell asleep, in which she was able to meet her best friend, apologize and reconcile with her, and the two of them continued to live their lives together. Nana became more and more demonic, and her boyfriend's apology was completely ignored, just like an evil spirit, repeating what she had done and the road she had traveled when she was with Xiaohong every day.

"Na~Na~"

A soft call rang out in the dormitory, and Nana opened her eyes in a daze, feeling like she couldn't exert any strength in her body, as if she was paralyzed. The only eye that could move turned around to see where the sound was coming from, but she couldn't see it, and then she felt a gasp from her neck, and her eyes were desperately squinting to see what was going on, but she couldn't see it. After a while, Nana's ears heard a long sigh, a voice she couldn't be more familiar with, and the sound came from under the bed, Nana's eyes widened, and cold sweat broke out in her head.

At this moment, Nana's voice suddenly sounded in Nana's ears.

"Good friends have to be back to back..."
