Mariko is living the life of a typical Japanese college student in the 70's, spending far more of her time balancing boyfriends and part-time jobs than on her schoolwork. She finds herself torn between a former boyfriend who's the tough, insensitive-but-sexy, type, and a new acquaintance who's more sensitive to her feelings, but who still acts childishly selfish at times. Will she choose one of them, or decide to go her own way?
