Just checked out ch 31 this morning.
Spoiler for Ch 31:
Okay, Reiji's "creep-o-meter" reading just jumped way,
waaay up. His previous actions were questionable, but I was willing to give him the benefit of the doubt becuase he had been through a lot, himself. Now though...
I enjoyed the development of Aoki's relation with Rin. It seems she is starting to open up to him, which is probably just what she need to heal the "scar" that Kuro spoke of.
The story just keeps getting better and better. It's too bad so many people can't get past their knee-jerk reactions to the surface appearance of the manga to appreciate that.
