I feel like the momentum of the story is going back to the starting chapters, especially around the festival, where As the reader we were able to see how deeply Konatsu feels about Koyuki. Maybe next chapter we get to see explicitly how Koyuki feels about Konatsu.
Volumes 5, 6 and half of 7 were a tour-de-force in terms of giving the characters a deeper emotional understanding of their own issues and due to how long it took them to be released, I've seen several readers feel fatigued, but now should be the time to really start paying all that build-up and development off with the interactions between the two. Koyuki would certainly be able to give a more proper answer to Konatsu's question from the previous year's summer festival. Actually I wonder if there will be a chapter where they go to the festival again since summer break is coming up and Koyuki's father suggested she take a break from cram school and go have fun once in a while.
I’d love to see a reiteration if the summer festival. I really think the next chapter can go two ways: it’s the long awaited confession chapter, or it’s that start of a new conflict chapter. Honestly I think and hope it will go the second way, mostly because we just got past major development, and I think that it would be a littler jarring to go straight into a relationship given how the pace has been going, and so we can see that realization of feelings ourselves. Neither character has said to themselves how they feel about the other, it was mostly us the reader deducting their feelings. I think the payoff would be great to see that character growth of acknowledgment of feelings. Also more conflict means the story isn’t over yet, really hoping this isn’t the final arc, although the journey has been very satisfying so far.
