My Girlfriend's Not Here Today Vol. 4 by Kiyoko Iwami

With that simple sentence, Fuuko confirms Nanase's worst fears and demolishes her already fragile trust in Yuni. As the couple grapples with who's responsible for what and how to move forward, they each come to the same conclusion: They don't want to give up what they love. But do Nanase and Yuni want the same thing?
