NGL, what I comment earlier is true, I think Hiyori(female ero-mangaka) would be great with Gou(master's brother), but gotta say, the thought of Master having relations with Hiyori sounds interesting and tantalizing to watch as well. And its not like Hiyori is romantically interested in Gou(though she is a big fan of his works), nor does Gou realize Hiyori(as herself) exists, so there would be no NTR here, but I still think I would love to see these two work together and kind-of expand both of their horizons in an organic way. And I feel like that won't happen if she sleeps with Master. Either way, next chapter will certainly be interesting. Can't wait =03!
