I don't know if Kuzushiro intends to show the girls' whole high school career but it's kind interesting that it keeps mentioning time recently, the class wants to win next time in their second and third year, Kanon wants to live with Saki after high school, Rinne wants to attend her sister's high school after making lots of memories in middle school, and of course the looming recital. As mentioned by others in here Kuzushiro is definitely capable of running a series for years (Living With My Brother's Wife isn't even their longest running series, Kimino Tamenara Shineru latest 14 years) and we are ""only"" 3 years into this one.
Anyway! fun chapter, nice to see everyone's evolving dynamics and for more characters to pickup on how Saki has a bit of a darker mindset at times.
