Not sure why, but i can see it coming where the grandma says how she likes someone, the guy starts to feel a pressure in his chest, then the misunderstanding clears up with some development.
I was also confused when I thought Taira (MC) was leading the class discussion about the Athletic Festival. Was his first name 'Ootani'? Did I miss a chapter? Is this Furi's dream, to be surrounded by Taira?
