Su Yang was an average university student in Shanghai when he received a system that allowed him to add points to things. The point system provided him with missions and by clearing them, he would gain points.

For He Gu, to be secretly in love is like a strong alcoholic drink. Obviously, once it flows into your system, dizziness, the loss of self-control and suffering will follow closely by, making it possible for anyone to be fatally attracted like moths to flames, and willingly endure the hardships.

While you made sure to not overdo it, I’ve become completely intoxicated…however, for every intoxicated feeling, you will inevitably wake up from it one day.

When Song Ju Han continued to act childish and recklessly destroyed He Gu’s tenderness for him, he had never imagined that the man has already been written into his destiny. Even more, he had never imagined that—the person brought to him by destiny—would one day want to escape…

Set on a giant, almost finished bridge between Sadogashima and Niigata. Abandoned by the government, the bridge, and the giant man-made floating island at the center, has become a city of criminals and societal drop-outs.

Set in the same world as Durarara, but 15-20 years later. There is almost no overlap between Etsusa Bridge and the other novels.
