Tiny and adorable when they first met, Rui – still just as adorable – now looms over his boyfriend, Yuujirou. Though they were little more than best friends at first, the confusion over their true feelings for one another smoldered until they confessed. Now every day passes with such overwhelming sweetness it's all they can do not to ask themselves, "am I allowed to be this happy?"

The final high school judo contest, the last summer of their high school careers, and beyond... the thought of his future with Rui makes Yuujirou's heart flutter.

A slow-burn love story between a diminutive, athletic teen and his towering, kind-hearted best friend as they journey the slightly bitter road to adulthood towards sweeter days.
