Don't analyze my eyes like a monitor refresh rate! But... since you care about my look, I suppose... I will also dress extra prettily just for our date! dummy!' / 【ハルカ部長のワンポイント指導】『いしき（意識）するよ！『ハルカ部長、オフィスのミーティング中にあなたと目が合うたびに、あなたの世界一美しい瞳を意識してしまって（意識して）、心拍数が限界突破します！』って…っ！瞳を意識する！バカ！/// 会議中は資料のスライドに集中しなさい！…でも、その赤くなってるあんたの顔、本当は凄く愛おしいから許してあげるわ！』.
