Getting over an ex is hard, especially when you're still sleeping with them! It takes Miwa and Saeko a while to let go of that final aspect of their relationship, but now they are both ready to move on and give new love a chance.
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.
