    Summary

    Giyuu Tomioka's world is quiet and predictable. Shinobu Kochou's world is textbooks and her older sister. They're just friends, trying to navigate college.

    That is, until their older sisters decide to meet.

    What starts as a simple, awkward double date between near-strangers quickly evolves into something else entirely when Kanae Kochou, a bubbly 22-year-old student, develops an immediate and overwhelming crush on Tsutako Tomioka, a composed 26-year-old doctor.

    Now, Giyuu and Shinobu are stuck in the middle, forced to watch as their sisters fumble their way into a relationship that changes everyone's lives—including theirs.
