Jiang Yubai tried again and again to cross the line.
Chen Jin went from restrained to out of control, which was a cross-border.
The two are pulled between reason and desire, distance and proximity, which is a constant cross-border crossing of psychological defense lines.
Every message is a signal,
Every wait is a signal,
Every movement is a silent cry for help and response,
They don't say "love" but they are sending and receiving signals all the time.
Intention: Every time you cross the boundary, you are taking a step forward; every signal is a test and a pull. Love means constantly crossing boundaries, sending signals, knowing the danger but still taking a step forward.
