"I am happily caught in your sweet love net, Haruka-san!" ...っ! C-Caught in my love net! B-Baka! Don't compare my love to a net! But... since you are caught, I will never let you escape from my arms, so stay locked right there! dummy!' / 【ハルカ部長のワンポイント指導】『つかまる（捕まる）よ！『ハルカ部長の仕掛けた、甘いヤキモチの愛の包囲網に完全に捕まってしまいました！もう一生逃げられません！』って…っ！愛の包囲網に捕まる！バカ！/// 逃げる気なんて最初からゼロのくせに！…捕まえたからには、一生私の腕の中から釈放（解放）してあげないから、覚悟しなさい！』.
