Where Begonia Flowers Fall

In the writings of traditional Chinese culture, Begonia is always intertwined with lingering love and longing. Its flower language hides "humble and bitter love", which is the deep love that is given silently and is timid to be spoken, blooming quietly among the branches and withering quietly in the years. College student Xiao Hu accidentally killed a mother and daughter in order to save them, and was sentenced to ten years. After he was released from prison, he opened a flower shop called "Begonia Rain" and met a girl in green, but he didn't know that she was the little girl back then. Can the most beautiful flowers bloom in the rain of begonias after seventeen years of longing, worldly perspective, and year-end love that is seventeen years apart? The ending is extremely sad.
