After the engagement annoucement, Yuri Tokikago and Keiju Tabuki have decided to move into a new apartment- which Ringo Oginome only finds out when she finds herself in Tabuki's empty, old house. But when she finds the change of address notice that Tabuki gave to Shoma, it reinvigorates her to go through with "Project M". Meanwhile, Kanba Takakura decides that if Shoma fails to get the diary soon, he is going to take it from Ringo by force.
