Bu Hanlu, a mysterious girl, recently learned a new skill-picking locks.This skill leads her and her friends to the observatory late at night, hoping to discover some exciting secrets.However, when they opened the observatory's door, they found it empty.At this time, the sudden appearance of security guards put them in trouble.In desperation, Lin Qian and Duanhou created a wonderful appearance that overlapped with the image of her sister in the comics, making Bu Hanlu mistakenly think that she was the ally he had been looking for for a long time.
In order to verify this suspicion, Bu Hanlu took advantage of Lin Qianyu's birthday to go to her house to check.In the process, she discovered that Lin Qianyu had a strange scar that suddenly appeared in 2000, which made her even more suspicious of Lin Qianyu's identity.However, just after the birthday celebration, Liu Yang accidentally discovered Bu Hanlu's bp machine and the secret that she had always believed that her sister was on another planet.This secret surprised everyone, and they decided to leave temporarily to give Bu Hanlu some space.
After leaving, Liu Yixian learned through online research that Bu Hanlu might have a mental problem.This reminded Lin Qianyu of her sister's strange behavior, and she realized that it was Lin Qianqian who was replying to Bu Hanlu's message.At this time, the girls in the dance room were gossiping behind Meng Huiyuan's back, and Fang Dawu was accidentally squeezed into the dance room.Faced with the cynicism of the girls, Liu Yixian stepped forward and stood up for Meng Huiyuan.This scene made Bu Hanlu see the power of friendship and strengthened her belief in finding her sister.
However, Bu Hanlu's application for membership was rejected by the Astronomical Society, which disappointed her.So, she asked Lin Qianyu to help her plead with the president.In the process, Bu Hanlu recalled the past agreement with her sister, which strengthened her belief.On the occasion of his birthday, Bu Hanlu rejected Bu's mother's proposal to go out for a meal to celebrate and chose to spend this special day with his family.Bu's father cooked a bowl of noodles for her and offered to send her to school the next day.Although Bu Hanlu was late because her father was not familiar with the school route, she still felt the warmth of her family.
At the school wall, Bu Hanlu met Lin Qianyu who was climbing over the wall.Lin Qianyu helped her climb over the wall and sneak into the school, but was stopped by patrolling security guards.In the process of escaping, Bu Hanlu felt Lin Qianyu's bravery and determination.In order to receive the information as soon as possible, Bu Hanlu looked around for a location in the school where the bp machine had a signal.Eventually, she received a signal on the rooftop that convinced her that her sister was contacting her in some way.
On the rooftop, Liu Yixian and Fang Dawu celebrated Bu Hanlu's birthday and made a birthday cake with their own hands.Although Bu Hanlu was not moved at first and even lost his temper, he was eventually moved by everyone's sincerity.At this special moment, Bu Hanlu made a wish and saw a flashing UFO falling in the sky in the distance.She firmly believed that this was a signal from her sister, which strengthened her determination to pursue her sister.
