Hey, everyone!

I'm looking for a shoujo manga, it was about a girl that recently started dating the guy. He did seem to interested in the relationship like putting his job before it, so she is bummed about it. Later she falls down the stairs and injuries a classmate and takes his place at his job, one of the days falling on her birthday. When he boyfriend wants to go on a date, which her friend yelled at him about, she says she can't but doesn't give an explain because she doesn't want him to know where she is working. After that, they about almost break up fight. So she goes to the job and she is in the costumes and faints and wakes up to see her boyfriend and they make up and stuff. Thanks for any help! 😀
