Chen Xinglan's startling glance in the coffee shop made Yu Nian enter his heart from that moment on. The two people were originally two parallel lines, but they kept intersecting under the pull of fate. They struggle in the bustling city and wander in real dilemmas. The sourness of not being able to love and the pain of not being able to seek are always with them. But even though his body was covered with scars, the feelings hidden deep in his heart shone like stars. This is their story, about heartbeat, about struggle, and even more about their persistent protection of each other over the long years.
Concept: In the face of reality, Chen Xinglan and Yu Nian are wandering between heartbeat and struggle. This sour love is the starlight in the darkness, illuminating each other's way forward, and also witnessing the persistence of love in human nature.
