If love requires a certain distance to be sweet, then they are sweet enough. Nan comes and goes north - when Song Nan comes, Sang Bei will come too.
The distance between Sang Bei and Song Nan is as far as the south and the north, but after all, they cannot escape the company of love and careful care. Song Nan and Sang Bei were childhood sweethearts but there was no love between childhood sweethearts.
Subplot: "Sang Bei, I'm going to film tomorrow, and we may not see each other for four months." Song Nan saw that Sang Bei had no reaction to what she said, nor did he hold back, so she turned around and left silently.
One day when Song Nan returned to the rest area on the set, a familiar figure looked at him. "Song Nan, I'm sorry. I miss you so much that I couldn't help coming to see you."
Purpose: Sang Bei likes Song Nan and silently protects her
