You never trust what either of them is actually feeling because they don't trust it either. Two girls skipping class together, existing in the same quiet space, and then suddenly that space becomes dangerous because something unnameable is happening between them. The show moves at the speed of a held breath, letting long silences say more than confession ever could. It's a romance where the falling in love happens in the gaps, in the moments when they're not looking at each other. The cost is that nothing explodes into clarity, and some viewers will find that unbearable. But if you've ever felt something real grow in the space between you and another person without either of you knowing how to name it, this show lives there.

Adachi spends her school days cutting class, until she runs into Shimamura, another student skipping lessons, on the second floor of the gym. The two high school girls quickly become close, passing the time with table tennis and talk about their favorite TV shows. Their personalities differ, but they are happy to share their days. Then Adachi's friendship turns into romantic attraction, and the relationship slowly starts to change in this gentle yuri romance based on the light novels by Hitoma Iruma.
