Finally a proper kiss between these two and even initiated by Akko.
Nice end to the 3rd volume.
Now the question is: how will they handle their new relationship as a couple (I don't think going back to being just friends is an option anymore )?
They will probably hide it from their firends and from school. Though, I guess Sugi is already suspecting there's more going on between them, esp. after Akko's little story. Sugi will figure it out soon.
