I also want to point out something that no one seems to talk about. When it comes to character development between the first years. Excluding Jimmy, Yacchan when he starts to change and bring out his "true self" to more people, Toono is the one that is pushing his development. Pushing for change.Or Yacchan tries to push that change for Toono. But not in Vis versa. Toono seems to be fine with their relationship. But what pushes Toonos growth is indeed Kashima especially given to recent events.
I feel like with Sensei pushing the release of Mermaid prince vol 3, and with the the chapter of Yarichin being close to release vol 8 we probably will be waiting awhile. Oh well. Also though I do enjoy Yacchan and Toono why does Kashima and Toono consider bland and boring? People complain when Kashima was being pushy in the beginning and now he has stopped and Yacchan going on the offensive we hear crickets? Also pairing like Yacchan and Toono is not that rare as I read plently of series where the characters that the MC gets with is a tsunadere like type. And when their are tropes were a character has to pick between the 2 characters lot of times they pick the Yacchan like character. So if you ask me, it quite the opposite.
