Episode 11 recap: Su Wei An returned to his country without saying goodbye.

The next morning, Su Wei An thanked everyone and felt a bit embarrassed, but Gu Yun Zheng hugged her from behind. Gu Yun Zheng said that his medical mission was over and he had to go back to his country. He hoped that Su Wei An would go back with him. Su Wei An didn't respond, and Gu Yun Zheng thought she was angry. Su Wei An denied it and said that she didn't want Gu Yun Zheng to change any decisions because of her.

They sat together and watched the sunrise, hoping that these beautiful days could last a little longer. On the way back, Su Wei An already felt very happy and didn't dare to ask for more. When Gu Yun Zheng was at work, he called his grandfather and informed him that he might not be able to come back for his grandfather's 80th birthday. His grandfather immediately guessed that Gu Yun Zheng must have a girlfriend, and Gu Yun Zheng didn't refute it.

His grandfather was very happy and asked him to bring his future daughter-in-law back as soon as possible. The reason Gu Yun Zheng wanted to return a bit later was to celebrate Su Wei An's birthday first. Gu Yun Zheng knew how to make a birthday cake because when he was young, his mother used to come back and celebrate his birthday. But his skill level was always limited, and only his grandfather accompanied him. Every year on his birthday, Gu Yun Zheng wished for his mother to come back.

His grandfather collapsed after eating the birthday cake due to diabetes, and when his father came back, he criticized Gu Yun Zheng. Gu Yun Zheng realized his mistake this time and said that he would never make a birthday cake again. Since then, even when Gu Yun Zheng celebrated his birthday, he would only go to a dessert shop to have a cake and then leave without taking it with him.

After Jiang Mu Ying returned home, she started gossiping about how far Su Wei An and Gu Yun Zheng had progressed recently. Su Wei An also mentioned that Gu Yun Zheng had confessed his feelings to her. Su Wei An suddenly received a call from her mother, who informed her that her aunt had been diagnosed with a movement disorder and hoped that her daughter could come back for a visit.

Originally, in the evening, Su Wei An was supposed to go and meet Gu Yun Zheng, but when she arrived at the door, she couldn't bring herself to go in. After all, she also had a movement disorder, and this illness could potentially be fatal and hereditary. So Su Wei An didn't want to burden Gu Yun Zheng.

After I left, Su Wei An began to pack his luggage in preparation to return to his home country. At first, Jiang Mu Ying didn't quite understand, but Su Wei An didn't hide the fact that she had developed a movement disorder. Jiang Mu Ying actually knew about it long ago when she found out that Su Wei An didn't bring the medical test reports in her notebook.

Su Wei An just didn't want Gu Yun Zheng to know about this. Jiang Mu Ying was saddened by Su Wei An's illness, and Su Wei An asked Jiang Mu Ying not to tell Gu Yun Zheng about it.

In the evening, Su Wei An had already packed her luggage and was ready to leave. There were too many memories here with Gu Yun Zheng. Gu Yun Zheng kept calling Su Wei An, but she didn't answer. Gu Yun Zheng could only call Jiang Mu Ying, who informed him that Su Wei An had taken a flight and left, but she didn't reveal the real reason. Gu Yun Zheng rushed to the airport disregarding everything, intending to find Su Wei An, but by that time, Su Wei An had already boarded the plane.

Su Wei An held onto the stone that Gu Yun Zheng had given her, but in the end, she couldn't help but throw it away in the trash bag. After returning to her home country, Su Wei An quickly returned to her home, where everything was still very familiar, just as it was when she left. Afterwards, Su Wei An started researching the relevant issues related to movement disorders in her home country. She temporarily didn't inform her mother about her own condition, and now the only thing she could do was to explore every possible means to seek treatment for her condition.

Su Wei An's father wasn't actually in a car accident. She watched a video of her father during the accident and, combined with the doctor's diagnosis, became more certain that her father had developed a movement disorder while driving. That's why Su Wei An was eager to find a way to treat the condition. However, Gu Yun Zheng, who was still abroad, immersed himself in his work every day, trying not to think about Su Wei An.

Jiang Mu Ying also showed Su Wei An a photo of Gu Yun Zheng, and now the only thing Su Wei An could do was to let him rest well. Su Wei An visited her aunt, who even contemplated giving up her beloved violin because of the illness.
