Beyond the Wall of My Heart Is You

The city was full of emotions, and I built a wall to isolate myself from all difficulties, but on the day I met Gu Yanshen, I was defeated. He is immune to all emotions, but is susceptible to my love and pain; we are saved in both directions, but are repeatedly pulled apart by misunderstandings and crises. Only after separation do we understand: outside the wall of my heart, there is always only you.
