I don't remember any pink arrows in these, but these are all the poly yuri mangas I know, is it one of them?

I suddenly recall this manga about a poly yuri relationship, but the only thing i could remember is that the manga was black and white ofc, but there were these graphic pink arrows sometimes. Please, if any of you remember something tell mee, i'm desperate! TT _ TT
