This is the description of the Japanese book 告白 by Kanae Minato. In the picture, in red, are two instances of a character I suppose to be a hiragana.
But I have never seen it and can't find it anywhere on the internet.
Through context I think it might be a contracted form of ここ, but is there even such a thing as contracting two hiragana in one? How do we call it so I can find more info of that on the internet?
I will very much appreciate if you guys could enlighten me on the meaning of it.
