Losing her mother at a young age, Misaki Yoko was raised amongst three brothers. Yoko is a slightly boyish girl who is bullheaded and hates dishonesty. Ever since she was young, she enjoyed the company of boys over girls. She starts a band with four of her boy friends and becomes the lead singer. Then one day, one of the members of the band, Tsukasa, gets a job at a bank in Tokyo. Due to Tsukasa leaving town, the band breaks up, and though Yoko finds herself lonely, she puts on a strong act in front of Tsukasa. She can't tell Tsukasa how she truly feels for him. On the day Tsukasa leaves for Tokyo, Yoko goes along with the band members to the airport to see him off. The guys get excited when they see some cabin crew ladies and Yoko has no idea why. She reminds them that even she can wear a uniform, but the guys only make fun of her. That's when Tsukasa tells Yoko he wonders what she'd look like dressed in uniform. This is when Yoko decides she wants to work as a Cabin Attendant.
