Searching for You All over the World

Leaving you is the happiest decision in my life... What is happiness? I don't have a clear answer. After losing my family, I even believed that I would bring misfortune. I don't know when I started, I can only use different shades of black to describe every scene and thing I see. To me, that is lonely. Unique color. Not long after I entered high school, a girl with fair skin and hair as silver as snow walked into my world. She is a painting genius who cannot see colors, but miraculously she can see the colorful colors in my paintings. Painting together under the moonlight, holding an umbrella together in the pouring rain, and enjoying a quiet dinner... With loneliness in our arms, we felt the taste of happiness for the first time in a long time. However, as we got closer to each other, I discovered that she, who had been deprived of her "color", began to lose her voice and ability to move one after another. Seeing her life passing by rapidly, I suddenly realized that the cause of all this was actually the secret hidden in the dark! In order to change her fate, I decided to pay the most expensive price - to completely disappear from her world... You are like the full moon, lighting up the darkness in my heart. And have I also shined that soft light into your clouded heart? If so, that would be great..
