I am looking for a one shot about a girl (I think wearing glasses) who can't speak loudly, and whose English is bad. Even her teacher has a hard time with her. A guy who sees her get bullied helps her. I remember the guy being good at fighting. At the end, there was a competition the teacher arranged. The competition for English speaking or similar. There was some penalty if the female lead couldn't speak well. The guy (or the girl, not sure) confessed their feelings on stage. I also remember the girl gave the guy a Band-Aid when he got hurt. I read it in KM. What shoujo/romance manga is this?
