After accompanying Subaru to Nana's apartment to return her key, Haru had an emotional reunion with her younger brother, Hachi. Then, suddenly, a man with a scary face busts into the room!

Then Subaru spots a magazine called Polaris in Yugo's bag—the very magazine that's serializing Subaru's novel.
