Ok, so this Manga might go on longer than expected? We are only getting to the part of the Manga where they become 2nd years. I'm assuming the 2nd year saga will only have 2 new girls(including chiyo), only so the harem doesn't get too oversaturated. And then finally end off with 3 year/epilouge portion. I'm happy with this development tbh. Prior to reading this chapter I thought we were like 2-3 more arcs away from the Manga ending. I think this is a sign of the Manga continuing for 4-6 more arcs.
