Dat mouthwash...and planned highjacking of the tea ceremony club. This one seems over the top in a number of ways. The amount of sugar is way too much for me but I suppose I can get into it. Not a bad start.
I think we can hope for some subtext. I haven't read any more than you, but as it seemed like people who bought this book on amazon also bought alot of subtexty moe manga i think this might be another subtexty manga, with a focus on teh moes. Plus the author has drawn this:
It's too much teasing to classify the entire series as yuri.
As more chapters come down the line, it'll be easier to decide whether just that chapter gets it or the series.
If that's the case...I'm all for adding a subtext tag. Caramel obviously has some not-so-subtle yuriness going on with her, but as you said gotta wait for more chapters (and let the waiting game begin).
And would be really good to see the story of Chocolate and Caramels relationship
