Chen Tingfan and Chen Nan have seriously discussed admitting to themselves that they like boys, admitting to others that they like boys, and admitting to their parents that they like boys, because this is the path they will take in the future.
They originally thought that as long as they crossed these three hurdles, they would be able to be together forever, but things went against their expectations. They had been desperately trying not to "separate", but in the end he said "goodbye" to him.
Intention: A love that is not blessed by parents and not recognized by the world. In the end, what prevents them from being together is not these two, but an accident.
