Episode 23 recap: Where the wind blows, the heart follows.

Bu Han Lu and Cheng Xiao Feng entered their final year of high school. Cheng Xiao Feng distributed a mock college application form to everyone, hoping that all classmates would set their goals and work hard in the last year. Bu Han Lu looked at the application form but didn't know how to fill it out. As an excuse, she invited Bu Han Lu to go to the observatory on an activity day.

Bu Han Lu went to the observatory to stargaze, and the Bu Han Lu who had once loved the stars returned. It was then that Lin Qian Yu asked Bu Han Lu why she wanted to give up. Bu Han Lu explained that her vestibular sense was even worse than that of ordinary people, so she couldn't become a pilot and wanted to give up studying astronomy.

Knowing Bu Han Lu's concerns, Lin Qian Yu went home and looked up information about pilots to see if he could help Bu Han Lu. As for himself, he wanted to study physics and learn how to save people with radio equipment like Jing Mu. Fang Da Wu decided to follow his mother's wishes and apply for education as his major, while Liu Yi Xian filled out an application for a local third-tier university to avoid worrying his mother.

Neither Bu Han Lu nor Lin Qian Yu had filled out their application forms properly. They coincidentally met on the rooftop and decided to let go of all their worries and randomly choose a major. Bu Han Lu wrote down the major that Lin Qian Yu wanted to apply for, and Lin Qian Yu, after a night of researching, chose a major related to the sky and aircraft design for Bu Han Lu.

Lin Qian Yu believed that even if Bu Han Lu couldn't become a pilot, she could still pursue her dream related to the sky. Both Lin Qian Yu and Bu Han Lu had their new goals, and in the following days, they studied diligently, driven by their ambitions.

After the final exams, Lin Qian Yu scored 540 points and felt extremely happy. When leaving school, Lin Qian Yu wanted to make plans with Bu Han Lu, but Bu Han Lu expressed a desire to stay at home and refused to go out. Worried that Bu Han Lu wouldn't face the situation, Lin Qian Yu went directly to find her and persuaded her to go out.

Lin Qian Yu knew that it was the first anniversary of Bu Han Yu's passing, and he couldn't let Bu Han Lu be alone at home facing the memorial. So he took Bu Han Lu out to have some fun. Lin Qian Yu planned a day's itinerary for Bu Han Lu to let her enjoy herself, and Bu Han Lu requested that Lin Qian Yu accompany her to a certain place after everything was over.

Lin Qian Yu accompanied Bu Han Lu to take photo booth pictures, play with dolls, and then they went to an amusement park, seeking the joy of their childhood. Bu Han Lu took Lin Qian Yu to the lighthouse and shared all the silly things she did in the past when missing her sister. She wanted to accompany Lin Qian Yu in remembering her sister together.

After Lin Qian Qian's passing, Lin Qian Yu had been suppressing the pain in his heart and hadn't let the tears flow. Under Bu Han Lu's encouragement, he finally faced the sky and let out all the longing for his sister with a roar, and tears involuntarily streamed down his face.

Bu Han Lu and Lin Qian Yu endured the toughest day together, and when they returned home, they had to face their parents' questions. At such a young age, they had to shoulder the responsibilities of adults. Bu Tian was worried about affecting Bu Han Lu's college entrance examination and wanted to delay the divorce proceedings until after the exam. Unexpectedly, Bu Han Lu overheard everything.

Bu Han Lu had known for a long time that her parents were planning to get a divorce. She directly told them that she agreed to their divorce and wanted them to be free. After Bu Han Lu made her stance clear, Bu Tian decided to go to the Civil Affairs Bureau the next day. Meanwhile, Lin Qian Yu's parents also returned home at this time.

Lin Qian Yu's parents decided to go abroad for further studies. They wanted to come back and inform Lin Qian Yu, but they continued to keep it a secret from their elderly parents. This made Lin Qian Yu feel uneasy. He didn't want to abandon his grandparents, but he also didn't want to let go of his parents in his heart. So he called Bu Han Lu, seeking her comfort.

Bu Han Lu told him about her parents' divorce, and Lin Qian Yu shared the irresponsible actions of his own parents. After comforting each other, they decided to boldly express their true feelings.
