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?!
as long as you're still the serious 
and stubborn Ren who loves me,
mientras sigas siendo el serio
 y terco Ren que me quiere,
mientras sigas siendo el serio
 y terco Ren que me quiere,
tant que tu es le Ren
finché rimarrai il Ren troppo serio
e cocciuto che mi vuole bene,
contanto que você continue sendo o Ren
certinho, teimoso e que me adora,
