Episode 20 recap: The girl who shines like light.

Bu Han Lu returned home and took back his comic from Bu Tian. Bu Tian questioned Bu Han Lu about the source of the comic, and Bu Han Lu had to lie and claim that he found it while tidying up. Bu Han Lu was worried that Bu Tian would find the comic again, so he called Lin Qian Yu to come to his house and entrusted the comic to Lin Qian Yu for safekeeping.

Upon receiving the call, Lin Qian Yu immediately went to Bu Han Lu's house. At the same time, Duan Chi also came to see Bu Han Lu, wanting to meet him. Duan Chi and Lin Qian Yu confronted each other downstairs with hostility, which made Bu Han Lu feel awkward.

When Bu Tian saw Bu Han Lu come downstairs, he immediately went to search Bu Han Lu's room because he found the four comics suspicious and felt like he had heard the contents of the comic before. Bu Tian didn't find the comic, so he had to rethink the contents of the comic himself. Inadvertently, he discovered that the words Bu Han Lu used to frequently say eight years ago were exactly the same as the contents of the comic.

Bu Tian suspected that the psychiatrist hadn't cured Bu Han Lu, so he went to see the psychiatrist again to inquire about the situation. Duan Chi, who had Bu Han Lu's company during the preliminary exams, performed well, so he wanted to see Bu Han Lu before the final exams.

Duan Chi talked to Bu Han Lu about the swivel chair test for the pilot exam and wanted to teach her some techniques to improve her vestibular function. Lin Qian Yu and the others asked Duan Chi to teach them as well. Liu Yang and the others didn't pay much attention to this test, but Lin Qian Yu reminded them to cooperate with Bu Han Lu, and they started learning from Duan Chi seriously.

Lin Qian Yu and the others were learning in a disorganized manner, so Duan Chi jokingly asked to compete with Bu Han Lu. Bu Han Lu thought that she had been maintaining her training and had participated in that battle, so she believed she would do better than Duan Chi for sure.

Bu Han Lu went confidently into the competition, but after the competition, she realized that her abilities were inferior to those of Lin Qian Yu and the others. Bu Han Lu couldn't believe it, and she couldn't pass the swivel chair test, so she tried several more times, injuring herself in the process, but still couldn't succeed.

Bu Han Lu felt extremely down, and Lin Qian Yu could only comfort her as an ally. Bu Han Lu suspected that she wasn't an outstanding fighter pilot, which could explain why she couldn't pass the swivel chair test.

Lin Qian Yu couldn't bear to wake Bu Han Lu up, so he continued to lie and make excuses to deceive her, hoping that she would no longer be upset.

After sending Bu Han Lu home, Liu Yi Xian and Fang Da Wu came to discuss with Lin Qian Yu whether they should wake Bu Han Lu up. They all believed that continuing to hide the truth from Bu Han Lu would require telling many more lies, and Bu Han Lu would never be able to move on from the shadow of Bu Han Yu's death unless they told her the truth. Therefore, they felt it was necessary to reveal the truth to Bu Han Lu.

Suddenly, Lin Qian Yu understood the meaning of an ally. He felt that Bu Han Yu wanted this ally to wake Bu Han Lu up at the right moment. So he decided to find the right moment to tell Bu Han Lu the truth. Bu Tian had cleared away all of Bu Han Yu's belongings and was waiting for Bu Han Lu to come back and ask about it, but she refused to confess the matter of the comic to Bu Tian.

Because Bu Han Lu refused to talk about the comic, Bu Tian cruelly revealed the truth about Bu Han Yu's passing, delivering a heavy blow to Bu Han Lu. Overwhelmed with grief, Bu Han Lu ran out, and everyone had to brave the rain to search for her. It was then that Lin Qian Yu realized that the girl who shone like light, the girl who was their leader, had disappeared in that moment.

Lin Qian Yu found Bu Han Lu at the observatory. Bu Han Lu saw Lin Qian Yu as her only ally, and all she needed was for him to tell her that everything about the Red Lotus Squad was real. Lin Qian Yu couldn't let Bu Han Lu continue to believe in the existence of aliens, so he had to confess the truth to her, letting her know that everything she least wanted to believe was true.

Lin Qian Yu's words dealt another blow to Bu Han Lu, pushing her to the brink of collapse. She drove Lin Qian Yu away and locked herself inside the observatory. Lin Qian Yu wanted to save her, so he went to find Lin Qian Qian, hoping that she would tell Bu Han Lu the truth.

Lin Qian Qian didn't want to be so cruel to Bu Han Lu, and she didn't want to disappoint Bu Han Yu. Lin Qian Yu blamed Lin Qian Qian for being selfish, only caring about Bu Han Yu and disregarding Bu Han Lu's feelings.

Lin Qian Yu told Lin Qian Qian about the fight between Bu Han Lu and her family and how she ran away and hid in the observatory, pleading with Lin Qian Qian to help Bu Han Lu. Lin Qian Qian, influenced by Lin Qian Yu's words, thought of Bu Han Yu. She knew that everything she had done was for Bu Han Yu, but she just couldn't bring herself to wake Bu Han Lu up.
