Kiritani Mirei plays the lead character Jonouchi Jun who is a researcher working in a paper manufacturing company and has been pouring all her energy into her work that she totally ignores what it means to dress up like a woman and care for her looks. As such, she has had little luck with men all along. However, when she realises that she is in danger of becoming a JSM, she gets together with her fellow female researchers to make an effort in changing their appearances and make themselves more beautiful. Mizukawa will play her colleague Maeda Mitsuko who is married with kids thus she is too busy with work, household chores and childcare to bother about her looks.When she was much younger, she used to be a go-gyaru by wearing mini-skirts, loose socks and heavy make-up but her fashion and beauty sense is somewhat different from the trends. Mizukawa commented that it may be embarrassing to play a woman who doesn't behave like one but as an actress, she finds this to be an interesting challenge.
Co-stars include Muroi Shigeru who plays Matsuura Eiko, an employee at a major cosmetics company which has dealings with Jun and Mitsuko's company and Suzuki Kosuke who plays Kunikida Osamu i.e. Eiko's assistant and feeds Jun and Mitsuko with the latest fashion and beauty advice.
