“Well, maybe that's it.”

“Possibly?”

Shizuka and Chiaki look at each other and say ‘Yes.’ Kaori has a pitiful expression and doesn't seem to want to go, but she has accepted it, so it's probably too late now.

I'm afraid that boy might confess to Kaori, but I can't imagine that Kaori would accept it. If you think about it that way, wouldn’t you feel sorry for him? At least, that's what I think.
