Yup, thank you!

I'm looking for a manga where a blond girl accidentally goes against another girl and fractures her arm, and now to make up for it she needs to work in a cafe with an high school theme (with weird ass German names that I don't understand). One of the cafe members is her previous friend who ruined her middle school life by revealing her secret (that she's a liar).

This.

Thank you!

Does anyone know the manga where the main character says something to a girl about "praising her voice" and how she "wants to listen forever" and shit, and the other one kind of takes it as a love confession?
This happens during school at a rooftop.
