There is a city living in everyone's heart, and the city is filled with various emotions. Sometimes, infatuation does not mean like, but hatred is just another form of love. Maybe, no one did anything wrong, maybe, everyone was wrong. He shouldn't have opened the city gate and let her walk to the place closest to his heart. And she shouldn't close the city gate tightly and let love go to a strange distance. Who will you open the city gate for, and who will you give the opportunity to give you a fatal blow at the place closest to your heart?
