This latest chapter is funny and cute. No problem there.
But I'm very annoyed at something this series has been doing for a while and this is the worst instance of it yet.
What the hell happened between chapters?! This is astronomically unsatisfying.
Last we saw these two they were having a major moment in their relationship, a confrontation that had been a long time coming and should have been revelatory for both of them about what their feelings are, what their relationship is and will be, what they had been doing up to that point and potentially so much more.
Instead we skip to school?! And they're... chill? What is their relationship? Mitsuki asked a very direct question and I guess Aya just didn't answer? That must have been awkward... Was it? What was the dialogue between these two in the moment? We don't have definitive answers to any of these questions because it seems there is a mandatory time skip between all chapters. Either we get the important events in 4 pages or we just have to catch up and guess when the next 4 arrive.
This latest chapter should have been a direct continuation of the previous one. Even if the conversation had to conclude with "I don't have an answer yet" or something along the lines of that trope, we needed to see it happen.
Aya answered the (reader’s) question at the beginning of the chapter.

That leaves up to our imagination what happened after she said yes, but given how Mitsuki is behaving, it was a crude “Ok I will be your friend”, with Koga not noticing Aya was hesitant, and then the party came to an end and they went back home (we need to remember Aya was on duty, taking care of the lighting (?) of the party and these mfs are too awkward to decide to hang out after the afterparty in order to talk it all out, they are dumb teenagers after all)
Being a 4-page manga, pacing is indeed an issue in this story, but I think that sometimes it is justified to just skip and give incomplete answers to the readers since the answers themselves are trivial. We know at the beginning of the chapter that they did not have a full conversation, because if they did, we’d get to see it. The author is simply skipping the boring parts and leaving it for flashbacks and assumptions which, given the format, is ok imo.
