When we were seventeen years old, there was a red line that seemed destined
First line:
Jing Heliao: You are not allowed to go beyond the line in the future. Anything that goes beyond the line will be mine by default.
Fu Yanqiu: One day I exceeded the line...
Second line:
Single meaning: Your names are from the same poem, right? Since ancient times, autumn has been a sad and lonely time. I say that autumn is better than spring.
Fu Yanqiu: Yes
Jing Heliao:... No
Third line:
Jing Heliao: The test paper is very helpful to me
Fu Yanqiu: My seventeen years old is also very helpful to your seventeen years old
Jing Heliao: Yeah
Fu Yanqiu & Jing Heliao
Concept: Youth is precious, the present is precious, study hard
