Bu Hanlu has always had a secret, which she kept deep in her heart and never revealed to outsiders.However, on that special night, she decided to make this secret public and lead her friends to explore this mysterious world.

In that room, Bu Hanlu's friends saw the comics left by Bu Hanyu and learned how Bu Hanlu came to believe this incredible story step by step.Chiyu Hayashi saw the image of the allies in the comics for the first time, which shocked him deeply.He understood that this secret belonged not only to Bu Hanlu but to all of them.

In order to take extra lessons, Lin Qianyu took everyone to his secret base.Bu Hanlu helped everyone make a study plan. Her seriousness and persistence infected everyone, making the students who had no interest in learning begin to study seriously.On the eve of the exam, Lin Qianyu was worried that he would become a burden to everyone, but Bu Hanlu saw his anxiety and accompanied him for the last one-on-one training at a secret base.Bu Hanlu's encouragement gave Lin Qianyu great motivation and allowed him to regain his confidence.

In this process, Bu Hanlu felt for the first time the joy and security of someone sharing secrets and fighting side by side.However, at this moment, Bu Hanlu suddenly received a call from Bu Tian, ​​and he discovered Bu Hanyu's comics.This news made Bu Hanlu fall into deep anxiety. She didn't know what would happen next.

With the summer vacation coming, Meng Huiyuan, Xianxian, Wu Wu, Liu Yang, and Chen Xiang met to rush to the provincial capital.They originally thought that Bu Hanlu would not come because of his grudge against Lin Qianyu, but to their surprise, Bu Hanlu got in the car together.In the car, Bu Hanlu held the Red Lotus badge tightly, and she decided to ask Lin Qianyu a question: Are you my ally?

Lin Qianyu stayed with her critically ill sister day and night, feeling exhausted physically and mentally.The arrival of his friends allowed him to finally breathe and regain his strength.In front of Bu Hanlu, he finally let go of his strength and cried bitterly.With everyone's prayers and company, Lin Qianqian's surgery went very smoothly.For the first time, Bu Hanlu felt how precious the power of seven people together was.

In the provincial capital, Lin Qian and Bu Hanlu found an astronomical telescope.Bu Hanlu saw the distant star T Cetus for the first time. She finally asked Lin Qianyu: Are you my ally?This time, Lin Qianyu admitted that he was willing to go with Bu Hanlu and accompany her in her long alien dream.However, I still don’t have the courage to say the phrase “I like you”.

Bu Hanlu learned to open the lock, and everyone went to the observatory to open the door late at night, only to find that there was nothing inside.At this time, the security guards also discovered their traces and chased them.In desperation, Lin Qianyu created a wonderful appearance that coincided with the image of her sister in the comics, making Bu Hanlu mistakenly think that Lin Qianyu was the ally he had been looking for for a long time.

Bu Hanlu took advantage of Lin Qianyu's birthday and went to Lin Qianyu's home for verification, and found a strange scar that suddenly appeared on Lin Qianyu in 2000.This made Bu Hanlu even more suspicious of Lin Qianyu's identity.However, at this time, Liu Yang accidentally discovered Bu Hanlu's bp machine and the secret that she had always believed that her sister was on another planet.Everyone was frightened and left hastily.

After a series of investigations and the development of events, Bu Hanlu's psychological problems gradually came to light.Lin Qianyu began to think of her sister's strange behavior and realized that it was Lin Qianqian who was replying to Bu Hanlu's message.The girls in the dance room were gossiping behind Meng Huiyuan's back. Fang Dawu was accidentally squeezed into the dance room. The girls in the dance room ridiculed Meng Huiyuan.Liu Yixian couldn't stand it and stood up for Meng Huiyuan, so she scolded those girls with insinuations.

Bu Hanlu's application for membership was rejected by the Astronomical Society, so he asked Lin Qianyu to help him plead with the president.However, just as Bu Hanlu's birthday was approaching, she refused Bu's mother's proposal to go out for dinner at night to celebrate her birthday.In the evening, Bu's father cooked a bowl of noodles for Bu Hanlu and offered to send Bu Hanlu to school the next day.Bu's father repeatedly mentioned Bu Hanlu and had no choice but to agree.

The next day, because Bu's father was not familiar with the school route, Bu Hanlu was late and met Lin Qianyu who was climbing over the wall.Lin Qianyu helped Bu Hanlu climb over the wall and sneaked into the school but was stopped by patrolling security guards. Lin Qianyu pulled Bu Hanlu and escaped.In order to receive the information as soon as possible, Bu Hanlu searched everywhere for a location in the school where the bp machine had a signal.Liu Yixian and Fang Dawu decorated the rooftop to celebrate Bu Hanlu's birthday and made a birthday cake by themselves.However, Bu Hanlu was not moved and even lost his temper.At this time, the bp machine finally received the signal, so Bu Hanlu stayed on the rooftop.Taking this opportunity, Wu Wu and Bu Hanlu untied their knot, Lin Qian and others attended the birthday party together.When Bu Hanlu was making a wish, she saw a flashing UFO falling in the sky in the distance. She firmly believed that it was a signal from her sister.
