I can totally get how Tokui feels. Think we all wonder how an ex we really loved (well, at least most of the men I know are like that, most women seem to move on far easier in my experience, but that is just anecdotal). I also kinda feel like... man, Aki made some big mistakes in life, but at least she got something she loved from it (a daughter) and seems to be doing well, that is good. Hope Tokui can find someone too. Personally hope it won't be Ishihara. Given the story, would feel very weird.
Thanks for the chapter
look forward to when you get 85 and 86 up, but no rush imo.
