Gu Lingzhi is not only the person he likes the most but also the person he admires the most.
When he was young, he told Ji Zhao what to do, what not to do, and how to deal with interpersonal relationships.
When he grew up, he used practical actions to teach Ji Zhao how to be a good person.
Ji Zhao always thought that Gu Ling was out of reach, until Gu Ling lowered his head and said to her: "I will always be by your side. People will grow old eventually in life. Since we all have to grow old, how about we do it together?"
