“Hey, I think this is a good place to live together.” “………… Haa.” During lunch break, I, Izumi Saku, let out a grand sigh. Right now, the person in front of me is Shiina Yukiho She is a woman who is under the mistaken impression that I am going out with her. I don’t mind that she’s deluding herself into thinking she’s in a relationship with me, but I’d prefer if she didn’t tell anyone in my class about it. However, she’s been telling everyone in class about it, and to top it off, she even claims she’s pregnant. I want to get away from her right now, but unfortunately, I can’t. The reason? Because we’ve known each other since childhood!
