"Every single happy future scenario I imagine naturally includes the ending where I marry you, Haruka-san!" ...っ! The Haruka ending included! B-Baka! Don't sneakily fix your life's multi-ending path with me! But... since I am the only main character of your future, make sure you love only me forever! dummy!' / 【ハルカ部長のワンポイント指導】『ふくまれる（含まれる）よ！『ハルカ部長、僕の描く幸せな未来の全シナリオには、当然あなたと結ばれるエンドが含まれる（含まれています）！』って…っ！ハルカエンドが含まれる！バカ！/// どさくさに紛れて人生のマルチエンディングを私で固定するんじゃないの！…でも、あんたの未来の唯一の主役は私なんだから、一生私だけを愛し続けなさい！』.
