[He hates the darkness. Yukine never really understood why he felt that way, so scared whenever he was left in the dark, but... It's not like he could control it. He just had to find a light source that gave out proper light, not that faint, blueish one that seemed to be around whenever one tried to light a candle.
His desire of wanting to find some light led him straight to the glowing words on the wall, of course. And it felt like he was being... nosy by reading them, so he tried to avoid doing that and instead just stick close to them for as long as they were lighted up, moving to another one when he saw it start to glow. If only he could find some company, that would make being in the darkness a little better.]
