Having come to Canada upon hearing the fake news that his mother Haruko is in critical condition, high school student Kaidou Haru meets a young boy named Ren. Haru is forced to spend the summer with Ren. Every day is a battle.

Haru's cafe "WHITE FANG" begins flourishing immediately after it opens. Even Haru and Ren's recently awkward relationship is getting back to normal. However, Aki is in a terrible mood.

Unable to stand being treated by a child by Haru, Ren leaves the house. Natsuo agrees to let Ren stay over when he suddenly shows up at his apartment, but Haru shows up just as he's about to grant Ren's request to do something that he "can't tell Haru about." Haru tells Ren to not come home ever again.
