Ohh seems like a storm is brewing once again. I really do wonder what will happen if Shiori does get her memories back and it seems that's not too far fetched, especially with how things are setup now.
There seems a lot of things Akio left out about the past still. Maybe there's some truth even of what Mizuki feared especially since old Shiori did actually know they weren't related. Kinda feel bad for both sides though.
Thanks for the chapter too~! Was kinda sad when I started reading this only to see that the last translation was 2 years ago but glad someone picked it up again. The story is quite interesting.
