Yurine doesn't have to study though, and Ayaka has been constantly studying since this all started. And those gardening club members had all kinds of time to dig in the dirt and sabotage their own club and punch each other out and stuff during their third year. It'll be fine.
Me, I want to see how the relationship works out - dates, intrigues, misunderstandings, romantic rivals, etc. I don't think these two are going to get together and then just shrug their shoulders at the viewer and stand in silence, not knowing what to do. Sure, the "are they ever going to get together?" question will be gone, but we all knew the answer from the first chapter, so it's not that big a deal.
And yes, I'm aware of how in denial I sound, lol I don't want it to end!
