It's not even over in the magazine yet, this seems to be a love triangle situation like in vol 5, but it get way more time to develop as it's on it's 3rd volume at the moment
@Nakanowatari yea kinda, but the next volumes are divided by arcs, take this volume, 8, as a "prologue" for the next 2 lol
71 to 80 is harem that include both sensei and then 81 to 90 for shark teeth sensei x shota and from 91 to probably 100 shota x tomboy sensei, latest chapter is 94 and who knows this gonna end with that, the "plot" dont get any better either honestly, and the joke of the kid having a micro penis dont go away
