Episode 10 recap: Gu Yan Zhi figured out Yan Mo's identity, and all of Yan Mo's efforts were in vain.

Historical records reminded Lu Fei Yan that Lao Sui would kill Gu Yan Zhi. Lu Fei Yan was worried that Yan Mo would refuse to leave because of this, so she didn't tell Yan Mo. Yan Mo dreamed of the scene where Gu Yan Zhi was killed by Lao Sui, and she was frightened by this dream. She was very afraid that it was a foreshadowing, so she hurriedly went to question Lu Fei Yan.

Lu Fei Yan came up with a reason, claiming that Yan Mo's dream was just her imagination under stress, and she shouldn't overthink it. He forced Yan Mo to leave. Yan Mo didn't say goodbye to Gu Yan Zhi. She believed Lu Fei Yan's words and planned to leave and return to the future, but she still felt uneasy.

Seeing Yan Mo's unease, Lu Fei Yan was also afraid that Yan Mo would never forgive him if she knew the truth. So he decided to tell Yan Mo the truth. Lu Fei Yan didn't want Yan Mo to continue making mistakes, but Yan Mo refused to listen. She would rather sacrifice her own life than leave.

Yan Mo ran back to save Gu Yan Zhi, while Gu Yan Zhi was meeting with Lao Sui, wanting to have a final talk with him. Lao Sui didn't think he did anything wrong. He believed that everything he did was for the sake of Gu Yan Zhi, but Gu Yan Zhi had changed.

While Lao Sui was busy explaining to Gu Yan Zhi, Wei Wei quietly approached them, wanting to kill Gu Yan Zhi and hide the secret of the car accident. Lao Sui couldn't let Wei Wei kill Gu Yan Zhi, so he fought with Wei Wei. In the end, he managed to subdue Wei Wei and took away his knife, but at that moment, Yan Mo arrived.

Yan Mo was overjoyed to see that Gu Yan Zhi was safe. She hugged Gu Yan Zhi to calm down, while Lao Sui was disturbed by hearing Yan Mo's voice. Lao Sui felt that his relationship with Gu Yan Zhi had changed because of Yan Mo's presence, so he wanted to kill Yan Mo.

Gu Yan Zhi wanted to save Yan Mo but couldn't stop Lao Sui. Eventually, Yan Mo was stabbed by Lao Sui. Little O and Lu Fei Yan arrived in time and blamed Yan Mo for not valuing her own life for the sake of Gu Yan Zhi. They asked Gu Yan Zhi to let go of Yan Mo's hand so they could take her away.

Lu Fei Yan said that Yan Mo and Gu Yan Zhi were not from the same world. Yan Mo would only be safe if she returned to her own world, so she asked Gu Yan Zhi to let go.

Gu Yan Zhi didn't know what was going on with Yan Mo. In order to save Yan Mo, he let Lu Fei Yan take Yan Mo away.

Gu Si Yu sent a message to comfort Gu Yan Zhi, but she felt a little disappointed because Little O was not with her. So she went to a street stall to drink. While Gu Si Yu was eating barbecue, she was harassed by a few drunk men and almost got into a fight with them. Fortunately, Little O appeared in time and saved Gu Si Yu.

Little O saved Gu Si Yu, but his system malfunctioned after being hit by several bottles thrown by the drunk men. After Little O collapsed, Gu Si Yu discovered that he wasn't bleeding and his hair was filled with electronic parts. That's when she realized that Little O was a robot.

Gu Si Yu went back and examined Little O's system. She found out that Little O's robotic system was still in the development stage, but the system in his body was very advanced. So she suspected that Little O wasn't a current research achievement. After learning about the situation, Gu Si Yu immediately went to find Gu Yan Zhi and explained everything. Gu Yan Zhi, combining with Yan Mo's strange words and actions before, finally understood that Yan Mo was a person from the future.

Yan Mo's identity was discovered, triggering another time rewind and causing a butterfly effect. This time, the time was pushed back three months. Yan Mo, unaware that time had been pushed back again, woke up thinking everything was fine. She hurriedly went to the research institute to find Gu Yan Zhi, but to her surprise, nobody there recognized her.

Yan Mo realized that nobody knew her, and that's when she realized the time rewind had happened. Even Little O's memories had been altered this time, and he had no knowledge of what had happened before. Little O worked at a fried chicken shop, and he arranged for Yan Mo to work there too, while also keeping an eye on the research institute across the street.

Yan Mo frequently visited the research institute and wasn't focused on her work, which made the store manager unhappy and almost cost her the job. She had to use a new popular fried chicken recipe to impress the boss, Zhou Han Zhang. This time, Yan Mo didn't get involved in Gu Yan Zhi's life, and history was following its original trajectory. Soon, Gu Yan Zhi was going to meet Song Ranran.

Lao Sui gave Gu Yan Zhi a ticket to a concert, where Song Ranran would perform. However, Yan Mo couldn't let go of Gu Yan Zhi, so she couldn't help but go to the venue to witness Gu Yan Zhi and Song Ranran's meeting. Gu Yan Zhi and Song Ranran met under a billboard according to the historical trajectory, and Yan Mo watched from a distance with tears rolling down her eyes.
