The e-mail Ren sent prompts Haruko to come to Japan all the way from Switzerland. Eagerly looking forward to seeing Haruko again, Ren innocently bubblles with excitement. But believing Haruko may notice how his relationship with Ren has changed, Haru is unable to show genuine excitement for Haruko's visit. When Haruko finally arrives at the Kaidou family home, Ren tries to tell her what he's thinking, but... A storm named Haruko has suddenly arrived at the Kaidou family home! What will happen to the brothers' quiet life?!

Eu não consigo entender 
 o motivo dele me tratar assim.
