Before he appeared, everything was dark and no light could be seen, and the same was true in life. Everything was terrible, and every day was hazy. Until he appeared, things changed and things got better. So, I think, he is that beam of light. Follow the light, chase the light, seize the light and become the light. "You broke into my world by mistake, and my world has been bright since then."
