A romance of convenience between two college women soon becomes the real thing. 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 have other options. Miwa and Saeko are loving the couple life, but a miscommunication in the bedroom proves to be more of a threat to the easy rhythm of their relationship than either thought possible. After all, the past is hard to leave behind, especially when Miwa is invited to a reunion with some of her high school friends, including the first love she never really got over.
