Oh, ok. In that case, it's safe to assume that's the side effect of Ruruka's candy. It seems like Ruruka's candies each have some sort of highly addictive drug, as seen as when she attempted to use it to get Juzo to kill Ryota and Kirigiri, she expects it to have some sort of neurological effects. It's possible Ruruka made the candy used when kissing Yoi-chan with some sort of physical effects, possibly highly potent enough to cause yellowing of the eyes at a mere lick. Though this is clearly possible in real life, we have a 15 year-old fashionista taking over the world in this series so that'S not out of the question.
