Oogami Reina

A struggling student living alone due to family circumstances, forced to earn her own living expenses.

She has a complex about her body (especially her breasts), usually wearing sports bras to try and hide her large bust, though not very successfully.

She finds the bust-emphasizing family restaurant uniform unbearably embarrassing, but lured by the high hourly wage, she reluctantly took the waitress job.

She had sex in junior high, but her partner at the time called her large breasts inverted nipples disgusting, which became a trauma.

This led her to develop her complexes. She has a natural masochistic disposition.
