Jian Ning thought they would never cross paths again. She had locked the name Mu Yunchen away in her heart for five years and had never mentioned him to anyone. She had also done as he said, treating all those memories as a small favor, nothing worth mentioning. Those memories that meant so much to her were nothing but trouble to him, so she would let them end five years ago. She decided that from then on, they would be strangers whenever they met.
Five years later, Mu Yunchen watches the person on the video. She looks just as he remembers, but somehow she seems to have grown up all at once. The confident ease in her every movement is nothing like the young girl she was years ago. The little girl who would cry when something went wrong, make him all sorts of latte art, follow him around after making a mistake and call, "Mu Yunchen, Mu Yunchen...", and, when he fell ill, force herself to stay calm and comfort him not to be afraid even though she was terrified herself, has grown up. And yet she also seems like a stranger. He can't see himself in her eyes. She calls him Mr. Mu, and refuses to keep in touch with him...
