Episode 20 recap: Li Ran unexpectedly won the competition.

Back in the summer of 2017, Cheng Yu Shan had just finished school and was preparing to go home when she saw a group of people beating up another person on the roadside. Little did she know that the person being beaten was Li Ran. At that time, Li Ran caught a glimpse of Cheng Yu Shan passing by, but she didn't help him. Instead, she silently bought some medicine and left it by his side before leaving. All of this was noticed by Li Ran.

As the math competition and robotics contest were about to begin, Cheng Yu Shan was getting ready for her exam in the morning when she was surprised to find Jiang Qing Lang waiting for her at the door. Today, Jiang Qing Lang's father personally drove Cheng Yu Shan to the exam, and her mother happened to see this scene.

In the car, Jiang Qing Lang tried to make Cheng Yu Shan less nervous by telling jokes and preparing breakfast. Before leaving, he even gave her a piece of chewing gum, hoping that she would feel more anxious during the exam.

Li Ran also arrived at the competition venue with his own robot. Today's competition was a duel. On the other hand, Cheng Yu Shan was still a bit nervous before her exam. When Li Ran participated in the competition, many other team members were being interviewed, but Li Ran and Chen Jin went unnoticed.

Now it was time for Li Ran's robot to engage in the duel. In fact, Li Ran didn't know if he would be able to win. On the other side, Cheng Yu Shan was still working on her math problems. She came across a question she didn't know how to solve, but suddenly remembered the problem-solving techniques that her teacher had taught her. Cheng Yu Shan took a deep breath and found a way to solve the problem.

Li Ran was the last one to enter the arena for the duel. The opponent's robot was very advanced, while Li Ran only had one controller. As the match was about to begin, Li Ran took a deep breath, and the competition officially started. Due to its small size, Li Ran's robot was at a disadvantage throughout the match. However, to everyone's surprise, Li Ran managed to hit the opponent's robot in a vulnerable spot, causing severe damage.

The opponent didn't back down either. At the last moment, just as Li Ran's robot was about to be destroyed, another mini robot emerged from inside and targeted the most critical part of the opponent's robot. The opponent's robot lost control completely, and Li Ran won the match. He was ecstatic to win the competition in his first attempt.

After receiving the trophy, Li Ran's first instinct was to quickly ride his bicycle to find Cheng Yu Shan. Along the way, he was filled with anticipation, wanting to share the good news with Cheng Yu Shan as soon as possible. However, just as he arrived at Cheng Yu Shan's doorstep, he saw Jiang Qing Lang escorting her back. In the end, Li Ran didn't get the chance to share the trophy with Cheng Yu Shan.

Soon, it was time for the release of the math exam results. Everyone gathered in front of the big screen, anxiously waiting for the final scores. To everyone's surprise, Shen Yao dropped from the top three to the eleventh place, leaving classmates astonished. Unexpectedly, Cheng Yu Shan scored over five hundred points, bringing joy to everyone. At the same time, it was announced that Li Ran had won second place in the grassroots competition. Class 11 students were thrilled for Li Ran, and at that moment, Li Ran felt proud. Their efforts had paid off. They returned to the classroom together, while Shen Yao, hiding in a corner, felt envious. Later, it was revealed that Sang Xia was the one who tampered with Shen Yao's medicine.

Upon returning home, Lei Ming received a court summons. Cheng Yu Shan's foster father began trying to arrange a marriage between Cheng Yu Shan and his nephew, as the nephew was wealthy and it would improve their family's living conditions. Cheng Yu Shan, of course, refused to compromise easily. Just then, the phone rang, and her foster father forbade her from answering it. He even wanted to control Cheng Yu Shan by secretly recording videos. In the end, Cheng Yu Shan, unwilling to accept this, left home directly to find Sang Xia.

Sang Xia was there to comfort Cheng Yu Shan all along, and Cheng Yu Shan didn't blame her mother because she couldn't even protect herself, let alone take care of her. In the morning, when Li Ran was having noodles, he encountered Cheng Yu Shan's foster father. Li Ran intentionally followed him, attempting to steal his phone. However, he was caught in the act. Fortunately, Jiang Qing Lang suddenly appeared and they teamed up to not only fight Cheng Yu Shan's foster father but also allowed Li Ran to take a look at his phone.

Jiang Qing Lang could sense that Li Ran also had feelings for Cheng Yu Shan, so he wanted to compete with Li Ran fairly. Instead of answering him, Li Ran turned and left. Mr. Wang brought up the legal lawsuit to Lei Ming and demanded a compensation of three million yuan. Although Lei Ming knew that the road ahead would be difficult, he refused to compromise easily.
