"...you know how light is invisible? Like⁠— Light rays in of themselves aren't visible to our eyes. There are things we can detect in the visible light spectrum, but light itself, traveling through space, has no shape, no form to be seen," Mingyu voiced quietly, expression pensive as he lingered outside his apartment door, back to Fox.

"But we know it's there. We can see how it illuminates our world, can tell when the light goes out. Even with our eyes shut, we can feel the warmth from the sun."

He turned to look over his shoulder, smiling again, expression set with determination.

"You do that for me every single day, Huli. The illumination, the warmth. And you can ask anyone who's crossed me about my darkness." The smile gained that newfound knife's edge again, and he opened the door. Flipping on the light switch, he stepped in, expecting Fox to follow.
