I'm loving this manga more with each chapter.
It's kind of weird to see Yoko doting on Shino instead of Ayaya..oh wait, wrong series.
Yoko and Shino were already friends long before they met Aya. In fact, during elementary school Yoko was asked by Isami to keep an eye on Shino. So, nope, Yoko doting on Shino is not weird at all.
