The Lost Moon of the Sea

I called him Hai, saying that he tolerated me like the sea. In his arms, I would never feel cold. No matter how much depression and sadness he feels, they will be melted away by his gentleness; he calls me Yue, saying that I am like the moon, giving him soft light in the dark, so that he will not be afraid of the dark. I still remember the look in his eyes before he died. The blood melted drop by drop on the sky blue dress. It was his blood. I didn't cry, I just looked at him quietly and closed my eyes. He was my test question. I passed the test but lost him. Conception:
