Haruki is on his guard against Uzuki's pranks, but is that was Uzuki is really planning?
She probably acted like she 
did today because of this.
ربّما تصرّفَتْ كما تصرّفَتْ اليوم متأثِّرة به

Elle fait peut-être pareil,
aujourd’hui.
Probabilmente,
 oggi si è comportata così a causa sua.
Ela só deve ter assistido 
quieta por causa disto.
