The writing is not good and be careful
The male protagonist killed the female protagonist with his own hands for the sake of his wife, so the title of the book means the four characters "Snow Ashes and Spring Roots". When taken apart, it represents four images, and when combined, it represents a burned-out love.
Later, the male protagonist's friend felt that his conscience could not bear it, so he told the male protagonist all the facts. The male protagonist broke down and ran to the female protagonist's rental house, but he only saw that the whole room was filled with his portraits.
The male protagonist held the female protagonist's ashes and stood alone under the female protagonist's rental house. The male protagonist personally killed everyone who had ever harmed the female protagonist.
In the end, in order to die for his love, the male protagonist ran to the place with the largest traffic volume and stood there. In the end, he was knocked into a vegetative state and did not wake up.
Concept: Once the protection of love is loosened, the sharpest edge always comes from the trust given by the loved one.
