I have a feeling this series runs as long as Junjou Romantica, that is, as long as JR is not finished, neither will this one be. They both take place in the same universe, and characters sometimes cross over in the background.
Pretty sure it will run till after JR since it started later too. Also I hope it does lol I cant imagine being both JR and Sekai-less ╥﹏╥
I hope they continue even after Ritsu "completely falls in love" and lets Takano know. They should move in together (like Usami and Misaki in JR) and get engaged, and have a lovey-dovey newly-wed life while trying to hide that from the rest of the Shoujo dept.
It probably will cuz Onodera still has to deal with his family although they kinda made it clear that he doesn't have to inherit
Well, at least his dad doesn't care that he doesn't inherit. His mom is still a bit frantic about him dissolving his engagement with An.
So, maybe this year, the manga will finish. It was long and I see Ritsu takes his time, but I still love it
