LOL!! With the way it throws plot twists and setbacks, you think it would never end. I'm not 100% sure if it will end anytime soon but we have nearly caught up to the official website and with the way the FL speaks of her plans coming to a close end, it seems its closer to finishing. I wouldn't be surprised if the story somehow stretches out longer and we (readers on mangago) have to wait a little bit longer (for not only the original to post a new chapter and for which-ever kind soul is uploading it on here to purchase, edit and upload it) It's why I hoped it would end within these next few chapters or we might have to wait a while

All I can think she could mean rn is.. earlier in the story, Sumire mentioned how she wanted to use Kippei against Karin in her revenge as "best friend stealing her friend's man." I know her plans kept changing and adapting throughout, but in one of the recent chapters (ch 80,) she mentioned how she would be going down with Karin in the end.. does that mean she plans to publically expose her affair with Kippei, too, which would put all three of them in a bad position? (It would destroy Karin and Kippei's reputation, but it would also damage Sumire, who would look like a backstabbing friend in the public eye.. worse she was seen at matchmaking parties and with another man so people's view might see her as a gold-digger too.) I did wonder how she planned to let Karin find out about that, especially this late into the story. Another possible option is that she could just be referring to exposing her past identity. The chapters on here are nearly caught up to the original website, so hopefully, the story is nearing its end.
