@wolp The school festival was basically:
"I like you - but you already knew that."
"No I didn't!"
"Oh, I guess I didn't tell you? I'll say it again."
They walk away from the crowd, 'talk about all sorts of things the way they always do,' and next chapter is back to shogi.
We know Rei likes Hina (obviously) and Hina realized how much she likes Rei - but that isn't a very clear-cut acknowledgement that they've moved from friends to dating. Like, what did Hina have to say as a real response to Rei being serious about marriage lol?? Did he do takesy-backsies if she's uncomfortable with it, or was she like 'yeah let's get married when I graduate!'
I know dating was the obvious result of the school festival but we skipped seeing the official confession and jumped straight to them kissing. Which... is very Rei, now that I think about it XD I'm just surprised that this is the first in-text confirmation of the school festival's aftermath.
