“People start dating surprisingly quickly, huh?”

Yukihisa was just an ordinary student with ordinary aspirations. Seated across from him was his childhood friend, Shiho. With that said, while they’ve known each other for a long time, they aren’t particularly close. While nursing soft drinks in the aftermath of a group date event, Shiho muses about relationships when she suddenly proposes the idea of practicing how to be in a relationship and makes Yukihisa her partner. Practice would give them both confidence when they decide to pursue a partner in the future but perhaps there’s more to Shiho’s proposal?

And thus, Yukihisa and Shiho’s practice as boyfriend and girlfriend begins.
