well, ogawa chise is her pen-name for BL manga. She writes shoujo under another name
well ok, but that was a yaoi manga... and i checked on baka updates her other name is takagi shigeyoshi. still doesnt explain higashi
It's probably a translation mistake.
this should explain it. read the notes http://www.mangago.zone/read-manga/ienai_itami_o_daite_iru/bt/259471/Ch0/37/
the author of the manga is ogawa chise? so why at the end in the mangaka notes shes saying she is higashi?
or is that someone else? idk for sure great work.
