Everyone was water in a lake in their previous lives. Some people transformed into clouds, some into snow, some into rain, and some into leaves after several reincarnations. Snow loves water, but she is worried that people will trample on her unscrupulously due to the hardness of the ice in the lake in winter, so he turns into white silver sand and wraps her tightly. If people trample on Snow, they may let her go. Rain loves the lake. Although people have a good relationship with water in summer, the sun in summer will turn the water in the lake into steam and exhaust it, so he sacrifices himself to preserve the water. Ye Zi and Hu are friends. She gives him the life to live, and he silently shields her from the harm from the outside world. There are always corners that the sun cannot reach, but darkness can swallow everything silently. Darkness loved the lake, but once the sun came out, she no longer belonged to his arms, so he hugged her greedily and refused to leave since he no longer shared time with the day. From then on, winter ushered in. In the end, the water lost the summer rain, lost the long night, lost the winter snow, and lost the autumn leaves. From then on she was left alone. In order to survive, she could only rush into the sea day and night and rush eastward without stopping. The four seasons were like spring and autumn, no rain, no night, no snow, no leaves. Later, she was reincarnated several times and turned into rain and snow, protecting those people in her past from generation to generation. But no matter what she did, she could no longer find their shadow in this vast world.
Concept: Everything in this world is just a circle, starting from the beginning and ending at the end.
