Sakiko Kinoshita is in love. Unfortunately, it is with her college professor, Takashou Chifuyu, who is already married and has rejected all the advances she has made toward him. When her mother decides to leave, Sakiko is unwilling to go and resolves to cover her own tuition and expenses. However, she has no job or means to pay for them. Just as she is about to sell herself to obtain the money, she encounters Natsuo, who not only saves her from making that mistake but also helps her take one step closer to what she desires most.
