>Kato, a dull college student, has a crush on Lisa-senpai, a fourth-year student in the same tennis club. >However, Yuya, a cheeky first-year student who lives in the same dormitory, interrupts them... This is the story of Lisa-sensei, the heroine from the first work, "The one I admire is over!", when she was a fourth-year college student.
So these last two works are mean to show both sisters are turbo sluts, all the men they dated with just pumped and dumped them and they don't mind because they're for the streets whether they're aware or not.
