Wildfire

Novel Summary
Tao Xiaodong had a blind brother. Tang Suoyan, gentle and calm, was his brother’s favourite doctor. As such, Tao Xiaodong loved Tang Suoyan as well.
Oftentimes, people lose sight of that which was easily gained.
Over the years, Tong Ning was so coddled by Tang Suoyan that he failed to appreciate how fetching this rare specimen was—dumping him without pause, and picking him up again when he had a change of heart.
Except, this time, he was a step too late. Tao Xiaodong had long made his move.
Tao Xiaodong looked at Tong Ning, telling him with a smile, “It doesn’t matter who Tang Suoyan used to be with. He’s mine now. As long as I don’t let go, you’ll never be able to take away what I hold onto.”
