As much as I want them to kiss, them not kissing is probably better for the plot. Just because of that, now she know he hadn't kiss before, and edging like this is more exciting in a way. Romance shouldn't be rushed or it'd be too boring
I feel like this manga has a potential to get anime adaptation. Good artstyle, good story and pacing, this is the same feeling as when I read Nisekoi or Gotoubun no Hanayome before it also get adaptation too
