Viz Media licensed the manga, and it describes the story:

Shy Miwa has always dreamed of finding love, but living in small-town Japan made finding the right match difficult—especially since she likes girls! Even going away to college didn’t seem to help, until one day her outgoing classmate Saeko suggests they might as well start dating each other since it’s not like either of them has other options.
 
At first it seems like things won’t work out as their personalities clash and misunderstandings abound. But when their casual friendship starts to become something more, Miwa begins to wonder—can a pragmatic proposal lead to true love?

The manga debuted in Shogakukan‘s Ura Sunday and Manga ONE in August 2018, and ended in March 2025. Shogakukan published the manga’s 14th and final compiled book volume in April 2025. Viz Media published the 14th volume on April 14.
