An unexpected (and chaotic) night with Mizuhara after she loses the key to her apartment leaves Kazuya feeling closer to the rental girlfriend than ever before. So much so that he’s seeing her everywhere he looks! Unfortunately, one of Ruka’s schemes gives Mizuhara the wrong idea about Kazuya’s relationship with the other girl. What’s love without a bit of chaos, right?
