She exists only to save her sister Shi Lan who suffers from leukemia and has a rare blood type. When we first met, she was crying in a panic, and her little muddy hands wiped her little face. Wearing a white shirt, he appeared in front of her with a smile like a spring breeze under the backlight of the setting sun... "Failing, declining, will Hu not return?" He thought of such a poem after hearing her name. She raised her harmless face and stared at him with her big innocent eyes, confused. Like a prince, he stretched out his comforting hands to the princess who fell into the mortal world, so beautiful. Her sister was excellent, sweet and lovable, and her prince carefully cared for her sister's delicate flower. Later, after her sister passed away, the love she had kept in her heart for him became a sin. Many years later, he understood what he meant, stretched out his hand to her affectionately and asked: "Shi Wei, Shi Wei, Hu is not coming back?" She asked with tears: Where will Shi Wei go? It was such a simple first encounter, but he easily entered her heart and took root in her heart. But to her, he was like a mustard that stayed in October forever, never waiting for the flowers to bloom. It is so easy for you to enter my heart, it only takes a first encounter, but it is so difficult for me to enter your heart, it took several years to enter your heart.
The plot is quite cruel, but also very real.
